深基坑施工边坡稳定性监测与支护加固技术设计

The Design of Slope Stability Monitoring and Supporting Reinforcement Technology in Deep Foundation Pit Construction

为了保障深基坑施工边坡的稳定性,文章针对深基坑施工边坡稳定性监测与支护加固技术展开研究。将施工区域的原始地质数据信息作为判定其稳定性的标准,针对坡顶沉降数据、邻近建筑物沉降数据或地下水位数据异常,设计了以HDPE防渗膜为核心的支护加固技术;针对深层水平位移数据(测斜)、坡顶水平位移数据和邻近建筑物垂直度数据异常,设计了以预应力锚索加为核心的支护加固技术。测试结果表明,研究成果可以实现对深基坑施工边坡稳定性数据的高精度监测,并且对应的支护加固技术可以有效提高边坡的稳定性。

In order to ensure the slope stability in the deep foundation pit construction,this paper studies the slope stability monitoring and supporting reinforcement technology in deep foundation pit construction.Taking the original geological data information of the construction area as the standard to judge its stability,the supporting reinforcement technology with HDPE anti-seepage film as the core is designed aiming at the abnormal settlement data of the slope top,adjacent buildings or groundwater level.Aiming at the abnormity of the deep horizontal displacement data(inclination measurement),the slope top horizontal displacement data and the perpendicularity data of adjacent buildings,the supporting reinforcement technology with prestressed anchor cable as the core is designed.The test results show that the research results can achieve high-precision monitoring of slope stability data in deep foundation pit construction,and the corresponding supporting reinforcement technology can effectively improve the stability of the slope.
