某软土区深基坑支护设计分析

Deep foundation pit supporting design in a soft soil area of putian

针对莆田某软土区深基坑,支护设计方案采用SMW工法桩。研究表明,通过对被动区的加固,提高被动区土体的抗剪强度指标,有效控制了支护结构的水平位移,保证其抗滑移和抗倾覆稳定。该方案具有施工方便、效率高的特点,且监测数据未见异常,达到设计目的。

For the deep foundation pit in a soft soil area of Putian,SMW construction pile is adopted in the support design.The research shows that by strengthening the passive area,the shear strength index of the soil in the passive area can be improved,the horizontal displacement of the supporting structure can be effectively controlled,and the anti-sliding and anti-overturning stability can be ensured.The scheme has the characteristics of convenient construction and high efficiency.No abnormality was found in the monitoring data,and the design purpose was achieved.
