基于“有压快排”的膨胀土边坡柔性综合防护方案研究

Research on flexible comprehensive protection scheme for expansive soil slope based on pressuring and fast discharge

膨胀土边坡稳定问题是国内工程建设中常见且灾害性强的技术问题,一旦边坡失稳将严重影响工程的安全运行并造成巨大的经济损失。提出了一种基于“有压快排”的膨胀土边坡柔性综合防护方案,并在丹江口库区宋岗码头岸坡治理中成功应用。数值计算结果表明:该方法能较好地控制边坡渗流场,并显著提升膨胀土边坡的稳定性。

The stability of expansive soil slopes is a common and highly disastrous technical problem in domestic en⁃gineering construction in various fields.Once a slope fails,it will seriously affect the safe operation of the project and cause huge economic losses.A flexible comprehensive protection scheme for expansive soil slope based on pres⁃suring and fast discharge was proposed and successfully applied in the practical treatment of Songgang Wharf bank slope in Danjiangkou Reservoir Area.The numerical calculation results showed that this method can better control the slope seepage field and significantly improve the stability of expansive soil slope.
