某隧道施工生活营地变形破坏特征及机理分析

针对渝利铁路长洪岭隧道1号斜井施工生活营地在建成后不久出现变形的现象,根据坡体的变形特征及工程与水文地质条件分析得出,坡体变形机理是生活用水及降雨渗入因平场处理不当产生的裂缝出现的局部变形,生活营地总体稳定,提出了以排水为主、压脚为辅的处理措施,以供工程参考借鉴。

On analysis of features of deformation and failures of some construction camp of some tunnel and their mechanism

According to the deformation of the No.1 inclined well construction camp of Changhongling tunnel along Chongqing-Lizhou railway shortly after the camp was built,the paper concludes the slope deformation mechanism is the partial deformation caused by the domestic water and rainwater which flow into the cracks caused by the insufficient flat field process according to the deformation features of the slope and the engineering and hydro-geological conditions and the camp is stabilized,and points out the drainage should be the primary while the pressing foot should be complementary,so as to provide reference and mirror for engineering.
