摘要
以浙赣线诸暨一号隧道坍塌为实例,叙述大跨、浅埋、偏压和不利地质条件下铁路双线隧道塌方经过,分析了塌方的成因,从山体的病害治理、加长明洞、洞身整治和变形整治等方面提出了塌方综合整治措施,对地表沉降沉陷、裂缝发展状况、护拱沉降、变形段和暗挖段沉降及洞身净空变化进行了监测。
Tunnel Zhuji No. 1 on the Zhejiang-Jiangxi Railway Line is specified as an instance of tunnel collapse. The large-span shallow-depth unsymmetrically-loaded double-track tunnel under unfavourable geologic conditions is described in detail as to its collapsing process, collapsing causes and comprehensive measures to treat mountainous damages, tunnel failures and tunnel deformation and extend the length of the open-cut tunnel. Ground surface settlement and subsidence, fracture expansion, protective arch settlement, deformation segments, subsurface-excavation settlement and clear height variations are monitored.
