摘要
武汉地铁2号线虎泉站-光谷广场站区间隧道沿线灰岩分布广泛,岩溶发育,采取钻探、物探等综合勘探技术,查明了岩溶分布特性。在区间隧道施工前,进行了溶洞注浆加固处理;并在此基础上,对区间隧道矿山法、盾构法以及明挖法等工法进行了综合比较,提出了适应本地层条件下的矿山法施工方案,达到了预期的效果,可为类似工程的设计和施工提供借鉴。
Along the tunnel of Wuhan NO. 2 subway line from Huquan Station to Guanggu Square Station, the limestone is widely distributed and the karst is well developed. The characteristics of karst distribution were ascertained using comprehensive exploration techniques such as drilIing and geophysical prospecting. Before the construction of the tunnel in this reach, the grou- ting and reinforcement of karst cave were carried out; on this basis, the mining method, shield method and open surface method were compared. The construction scheme using tunnel method that was suitable for the strata condition of this reach was proposed and the effects were as expected.
