4) frozen embankment
寒区路堤
1.
Based on the upper bound theory of limit equilibrium analysis,a formula is obtained for the plastic work rate that takes place in a frozen embankment consisting of a perfectly plastic material obeying the non-linear failure criterion with an associative flow rule in the plane strain regime.
假定冻土为理想弹塑性体,且符合相关联的流动法则,基于极限分析的上限理论,对非线性破坏准则的寒区路堤边坡稳定性问题,提出了一个既考虑了相关的非线性效应,又易于工程计算,且不失必要分析精度的实用方法。
5) cutting in frost area
寒区路堑
1.
It analyzes and puts forward main causes and influencing factors of artifical side slope slide of soil-cutting in frost area and forms a mechanical theoretical model.
通过对寒区路堑人工土质边坡滑塌现象的调查研究,分析了人工路堑边坡滑塌的主要原因及影响因素,在此基础上构建寒区路堑人工边坡稳定性的力学模型,通过对春融期处于饱和状态的边坡土体稳定性进行验算,提出宜排水固坡不宜削坡稳定的寒区路堑人工土质路堑边坡稳定措施,即采用土工材料下层排水,利用网状土工格室上层固土并种植喜水根深的马莲草的综合边坡稳定技术,取得较为理想的防治效果。
