Abstract

The engineering slope of Dongzhou Avenue is located in the complex zone with folds and fractures, which is a typical form of progressive deformation failure caused by the rainfall and engineering construction. Based on the analysis of its special slope engineering geological structure, a hydro-geological model is established in this paper, an unbalanced tension method of partial strength reduction for the pull-type slope is proposed to analyze the safety factor. The results of stability analysis show that: a thrust-type failure happen at first under the conditions, which an excavation is carried out, the water enters the sliding body along the fault, and the surface vegetation is peeled off. The second failure is based on the free surface caused by the first failure, a pull-type failure mode occurs from the middle part to the trailing edge of the sliding body, the calculated results of the unbalanced tension method of partial strength reduction are consistent with the field failure form. In this paper, based on the calculation of the traction slope unbalanced tension method, the calculation method of the overall pushing type control force with residual strength after the traction slope damage is established, and the corresponding control measures are proposed, and the operation results of the control measures for many years show that the management effect is good.
