Taiwan's high-speed rail subsides seriously

According to Taiwan's Dongsen News, the latest report on the subsidence of high-speed railways along Taiwan's surface has been released, among which there are three places in Changhua and Yunlin, and the problem of subsidence has continued to grow. Although the HSR Bureau emphasized that it is still in the safety zone, the super-pumped groundwater has caused the formation to accelerate its subsidence. Taiwan's “High-speed Rail Bureau” emphasized that there is still a certain distance from the 1,500th of the allowable warning value. The traffic safety is still flawless. However, the Yunlin County government stated that it will strengthen the investigation of ultra-pumped groundwater, and it is forbidden to newly drill water wells.

In many counties and cities in western Taiwan, because excessive groundwater overdraft caused the subsidence of the ground, in order to prevent such situation from continuing to deteriorate, the High-speed Rail Bureau began monitoring the situation of high-speed rail pier subsidence from 2003 onwards. In May and December 2013, the "executive office" of the Taiwan authorities also successively approved the implementation of the "Solution Subsidence Specific Solution Plan and Action Plan" and "Golden Corridor New Plan and Action Plan".

The report last year that was tested last year was released. Changhua and Yunlin have a total of 3 places, including 3.8cm in the subsidence of Changhua Xizhou, 4.4cm in the subsidence of Yunlin Huwei Station, and 4.6cm in the substation of High-speed Rail across 158 County Road. less.

In response, the “High Speed ​​Rail Bureau” emphasized that the current trains are all within safe limits. In the future, Yunchang District, the limited construction area on both sides of the high-speed railway will be changed from 60 meters to 150 meters, ensuring the safety of the high-speed railway bridge structure and safe operation.

For the results of the survey, the Yunlin County government stated that the use of underground water has resulted in insufficient rainfall in the county and the subsidence of the stratum has been more serious than in previous years. At present, the county government has cracked down on illegal groundwater extraction and cooperated with the “Water Resources Department” policy to strengthen investigations. Prohibit "new digging wells".
