The Research on the Determination of Slop Stability Coefficient Based on the Time Effect
Geological conditions is complex in the regions where China- Myanmar pipelines pass through,and lots of excavation and fill slopes were formed in the construction process,so these slopes should be studied and controlled.The slope stability factor is critical to designers and researchers in the slope engineering.However,the time factor is not considered in the calculation of the slope stability coefficient presently.In fact,the strength of rock and mechanical parameters are gradually reduced with time under stress,therefore the slope stability factor is ought to change with time correspondingly.In this paper,a function of the slope stability coefficient and time was established on the basis of the limit equilibrium equation,in which the time factor was introduced into the calculation of slope stability.Then,the theoretical calculation value was more suitable to the practical engineering result.In addition,this function was applied into the unstable slope evaluation of the China- Myanmar natural gas pipeline.
