In this paper , author has a summary to method of stability of arch dam abutment , research method of limited rigid body equilibrium and nonlinear fem simulation analysis for arch dam designs based on ansys 本文对拱坝坝肩稳定分析方法进行概述,较为深入的研究了刚体极限平衡法,以及非线性有限元在ansys中的运用。
So it is very urgent to describe a reservoir ' s flood season , to define reasonably it ' s limiting level , to find a real - time control method of limiting level and to establish an appropriate control model of limiting level 因此根据工程实际要求,科学描述水库汛期,合理确定水库汛限水位,研究汛限水位实时控制方法,建立切实可行的水库汛限水位控制模式等,是当务之急。
2 . taking five representative casualty loess landfalls on the house side - slope as examples , applying the method of limit analysis of soil plasticity and the ultimate equity method , the equation of the stability and gradient of the landfall is derived 2 .以5个典型宅基边坡伤亡性黄土崩塌为例,利用塑性极限分析和极限平衡法,推导出了此类黄土崩塌的稳定性与其坡度之间的关系。
There are two main innovate ideas in the dissertation . ( 1 ) supported by the results from the method of limit analysis of soil plasticity and the ultimate equity method , the author proposes the criterion of judging of stability of slope of foundation of a building 本文的创新点主要有:采用塑性极限分析和极限平衡方法,通过计算,提出了黄土地区宅基边坡的稳定性评价标准,即人工谷缘的坡度不得大于天然坡度。
In view of the fault existing in the method of limiting equlibrium condition for distinguishing soil mass stress state , this paper gives a simple and direct " " method based on the mohr ' s circle , which can be used in calculating soil mass stress state 摘要本文根据以往采用极限平衡条件式来判断土体应力状态所存在的问题,应用摩尔圈原理,从实用出发,推导出一个既简便又直观的" "应用计算法,供判断土体应力状态时使用,此法具有概念清楚,使用简明直观等特点。
