CHENG Qiang, ZHOU Yong-jiang, HUANG Shao-bin. Distortion and failure character of excavation slope in approximate level red beds[J]. 2004, 25(8期 刊出日).DOI:
By diagnosing the slope excavation diseases during the highway construction in Sichuan basin
the main distortions and failure types of slopes in approximate level red beds are concluded
that is accumulation formation landslide
bedding landslide
rip distortion of rock mass and rock mass collapse. The main geological character of slope in approximate level red beds is summed up; the three phases of slope distortion and failure
that is excavation load-off distortion
developing and widening of steep joint
distortion and failure come into being
are put forward; Finally
the failure mechanism is analyzed combined a project example.
