摘要
Abstract
Taking a high-rise building as an example,MIDAS-GTS model was established to study the mechanical characteristics of support structure during excavation of high cut slope construction.The results show that the lateral pressures of the three profiles calculated by the plane sliding method are 632.1,456.6 and 553.2 kN,respectively.The lateral pressures of the three profiles calculated by the strength reduc-tion method are 1 134,653.2 and 887.5 kN respectively,which are 1.2～1.5 times that of the plane sliding method.Therefore,the lateral pressures determined by the strength reduction method have a higher safety factor.With the continuous development of supporting structure con-struction,the maximum displacement and principal stress of the slope are reduced,which indicates that the supporting scheme adopted in this section can effectively control the displacement of the slope and has good safety and reliability.关键词
