高压线下软土地区基坑TRD组合施工方法

为保证高压线下软土地区基坑施工的质量，以南通市某一明挖区间工程项目为研究背景，研究了高压线下软土地区基坑TRD组合施工方法及要点，进行实例分析，根据试验结果验证了TRD工艺具有稳定性高、成墙质量高等优势，避免了基坑连续墙体的倾覆现象，对于加强基坑支护、止水防渗起到至关重要的作用。

TRD Combined Construction Method for Foundation Pit in Soft Soil Areaunder High-voltage Lines

In order to ensure the quality of foundation pit construction in soft soil areas under high-voltage lines, taking an open-cut section engineering project in Nantong City as the research background, the TRD combined construction methods and key points for foundation pit in soft soil areas under high-voltage lines has been studied and a case study is carried out. According to the experimental results, it is verified that the TRD process has high stability and high wall quality and other advantages, avoiding the overturning phenomenon of the continuous wall of the foundation pit, and playing a vital role in strengthening the foundation pit support, water stop and seepage prevention.
