When will Taiwan return to the embrace of the motherland recently become a hot topic.
The mainland map software not only discloses Taiwan’s street map, but also searches for “ Beijing-Taiwan High-speed Railway ” on the map, which can already display the Beijing-Taiwan High-speed Railway Line Map, and the end point is the Taipei Station of the High-speed Railway, which is eye-catching.
Construction of a high-speed rail direct to Taiwan has long been put on the agenda
As early as the 1980s, some people were discussing the construction of roads to Taiwan. In the 12th Five-Year Plan in 2011, the Taiwan-Beijing Expressway was listed. Later, on the 13th Five-Year Plan in 2016, the Beijing-Taiwan Highway was listed.
Recent " National Highway Network Planning " shows that mainland will build three expressways to Taiwan , two leading to Kinmen, one starting from Xiamen , one starting from Quanzhou , and the other leading from Fuzhou to Taipei.
Among them, the expressway from Fuzhou to Taipei will be completed in 2035.
How can I successfully arrive in Taiwan across Taiwan Strait?
planning is beautiful, but the mainland and Taiwan are separated by the Taiwan Strait. The Taiwan Strait is located on the continental shelf of the East China Sea, with a south entrance of about 400 kilometers wide, a north entrance of about 200 kilometers wide, and a narrowest point in the north is 130 kilometers. The seabed terrain is uneven, with an average water depth of about 60 meters, and a large wind and waves. How can the high-speed rail cross the strait and build it to Taiwan?
According to the existing method, there were only two ways to repair it. One is cross-sea bridge , and the other is the undersea tunnel
Solution 1: Cross-sea bridge
We might as well refer to Hong Kong-Zhuhai-Macao Bridge completed in 2018, and bridge adopts the "bridge-island-tunnel" plan to build

The Hong Kong-Zhuhai-Macao Bridge completed in 2018 is a bridge-tunnel project connecting Hong Kong, Zhuhai, Guangdong and Macau. It is located in the Lingdingyang waters of the Zhujiang River estuary in Guangdong Province. It starts from the artificial island at the Hong Kong Port near Hong Kong International Airport in the east, and spans the waters of the Lingdingyang in the South China Sea to the west and connects Zhuhai and Macau artificial islands with a total length of 55 kilometers. The Lingdingyang waters and the Taiwan Strait where the route of the Hong Kong-Zhuhai-Macao Bridge passes are also very busy waterways and the Taiwan Strait. Therefore, in order not to affect navigation, the Hong Kong-Zhuhai-Macao Bridge adopts the "bridge-island-tunnel" plan to build . That is to say, where there are routes, use the caisson tunnel, instead of the routes, use the bridge.

Solution 2: Undersea tunnel
The second solution is the undersea tunnel. Those living in the southeast coastal areas know that the location of typhoon login in my country is also near the Taiwan Strait waters, which leads to heavy winds and waves in the sea area, frequent impacts caused by tropical storms and typhoons. The storm surge disasters are extremely serious. Tropical storms and typhoons are affected no less than 5 times a year. The highest wind and waves can reach 32 meters, and the highest level 4 wind and waves are about 2 meters.

In such an environment, not to mention building bridges, sailing is very dangerous. Whether it is to build bridges, hoisting bridge decks, or sinking pipes like the Hong Kong-Zhuhai-Macao Bridge, faces huge difficulties, and the cost is astronomical .
So the undersea tunnel is a good plan for . The more reference value is English Channel Tunnel
English-French undersea tunnel, also known as English Channel Tunnel and European Tunnel, opened on May 6, 1994. It is a railway tunnel from the UK to France, located between the Port of Dover, England and the Port of Calais, France.
English Channel Tunnel consists of three parallel tunnels with a length of 51 km, with a total length of 153 km. The length of the tunnel in the seabed section is 3×38 km, making it the second longest undersea tunnel in the world and the longest railway tunnel in the world in the seabed section.
In recent years, we have to talk about tunneling, relying on China's shield machine , which is the top of the world. If China is the second, no one dares to say it is the first
shield machine
We all know that the hole made by the shield machine is a circle, but the high-speed rail is not only going to Taiwan, but also back. What should we do when we come back? Do you need to make another hole?
At this time, China's Nanhu rectangular shield machine solved this problem, with a width of 14.82 meters and a height of 9.446 meters. A rectangular hole can be made by digging a hole at one time, so that two rails can be laid to solve the problem of high-speed rail opening in two directions.

We have also designed three routes for Taiwan
In order to build the Beijing-Taiwan high-speed railway, relevant departments have held many seminars and proposed a variety of plans, which can be summarized into the North Line, the Central Line, and the South Line.
Three routes
North Line starts from Pingtan Island, Fujian Province, and ends from Hsinchu City, Taiwan Province. It is 120 kilometers long. The advantage is that this line is located in the narrowest part of the Taiwan Strait. From Pingtan to Taiwan, the straight line distance is only 68 nautical miles, and the shortest distance is. Built here, you can maximize the cost savings.
midline starts from Chongwu Town or Nanri Island in Quanzhou, and ends in Changhua or Miaoli County, Taiwan Province. The disadvantage of this line is that it is as high as 210 kilometers, which is twice the length of the northern line, but it is less affected by the typhoon.
South Line starts from Xiamen, first to Kinmen Island , then to Penghu Island , and finally to Chiayi City, Taiwan Province. This route is the longest, but it can connect Xiamen, Kinmen and Penghu together, which has relatively high economic benefits.
I know why
Whether it is a cross-sea bridge or an undersea tunnel, although the construction is not small, as long as the mainland makes up its mind, it is actually not a problem. The only question is when Taiwan will return.
At that time, the exchanges between the two sides of the Taiwan Strait will become very close, and language, culture, economy and trade will develop close ties. How many "Taiwan independence" can stop the family affection between the two sides of the Taiwan Strait?
