摘要
暗挖隧洞穿越建筑物时,地质发生变化,围岩应力释放,扰动范围变大,如果没有采取对应措施,容易对原有建筑物功能造成破坏,同时隧洞本身易发生坍塌事故,因此穿越建筑物时施工安全是关键。以南水北调中线工程向永定河生态补水工程为例,提供了一种暗挖隧洞穿越防渗墙施工工法,可以在保证施工安全的同时保持原建筑功能。
When a shallow buried undercut tunnel crosses a building,the geology changes,the surrounding rock stresses are released and the scope of disturbance becomes larger,which can easily cause damage to the original building function if no corresponding measures are taken,while the tunnel itself is prone to collapse accidents,so construction safety is key when crossing a building.This paper provided an example of the ecological water replenishment project of the South-North Water Transfer Project to the Yongding River,provided a method of construction of a concealed tunnel through an impermeable wall,which ensured construction safety while maintaining the function of the original building.
