| 摘 要： | 该文以非饱和残积土库岸路基为例,基于饱和—非饱和渗流理论,分析了不同库水位下降速率、饱和渗透系数等对残积土路基渗流场影响规律。然后采用非饱和土力学原理,分析不同库水位下降速率、下降型式等对残积土路基稳定性作用机理。

| Abstract: | Taking an unsaturated residual soil reservoir roadbed as example,the article analyzes the influence law of the different dropping velocities of reservoir water levels,saturated filtration coefficient and etc.on the residual soil roadbed seepage field based on the saturated–unsaturated seepage flow theory.And then the article uses the unsaturated soil mechanics to analyze the different dropping velocities and the dropping types on the stability action mechanism of the residual soil roadbed. |
