摘要

为了解南水北调中线弱膨胀土质下深挖方和高填方典型渠段破坏特点,首先采用Geo-Studio软件对2种渠段进行有限元建模,得到不同工况下的2种渠道断面模型;其次用SIGMA/W,SEEP/W模块及饱和-非饱和统一渗流方程,数值模拟完好和破坏2种工况下各渠段水平位移场及渗透压力场;最后用SLOPE/W模块及Bishop法,获得完好和破坏2种工况下各渠段最危险滑动面及安全系数,并提出具体测点布置方案,为典型测点布置和监控指标拟定提供参考。
        In order to understand the damage characteristics of the deep excavation and high fill typical canal sections of the weakly expansive soil in the middle line of the South-to-North Water Transfer Project, the article uses the GEOStudio software to model the two or two types of canals, and obtains the two channels under different conditions.Secondly, it uses SIGMA/W, SEEP/W module and saturated-unsaturated uniform seepage equation, numerical simulation of the horizontal displacement field and osmotic pressure field of each canal under both good and bad conditions. Finally, it uses SLOPE/W module and Bishop Method, obtains the most dangerous moving surface and safety factor of each canal under both good and bad conditions, puts forward the scheme of specific measuring points,and provides a reference for the preparation of typical measuring points and monitoring indicators.
