注浆治理浅埋暗挖隧道施工引起的地面沉降实例

Solution Using Grouting to Earth Subsidence Caused by Subsurface Excavation and Shallow Tunneling

通过采用注浆方法治理某一在高速公路路面下进行双峒、近距、浅埋暗挖隧道施工引起路面沉降的成功实例,对采用注浆方法治理地下工程施工引起的地面沉降进行了剖析,并对注浆工艺参数进行了探讨,提出了单位体积沉降量的水泥耗量的计算公式。

Based on the successful solution by grouting for the earth subsidence of a highway project caused by double-chamber, short- range, subsurface excavation and shallow tunneling, this essay analyzed the case, discussed its technological parameter, and provided a calculation formula of cement consumption by unit volume earth subsidence.
