摘　　要：随着我国高铁网建设,邻近既有线条件进行深基坑施工是经常遇到的情况,针对邻近既有线严禁水土流失,设备高度受限等,常规钻孔桩加止水帷幕造价高昂且存在许多弊端,商合杭高铁商丘站旅客地道出入口基坑采用冻结法施工,避免了水土流失和设备受限,大幅缩减了工期,对今后邻近营业线基坑施工具有教强指导意义。With the construction of China’s high-speed rail network, the construction of deep foundation pits adjacent to existing lines is often encountered. For the adjacent existing lines, soil erosion is strictly prohibited, the height of equipment is limited, and the cost of conventional bored piles plus water curtains is high and there are many drawbacks. The foundation pit of the passenger tunnel entrance and exit of Shangqiu-Hefei-Hangzhou High-speed Railway Shangqiu Station is constructed by freezing method, which avoids soil erosion and equipment limitation, and greatly shortens the construction period.
