【摘要】 地面塌陷是多种因素作用的结果，既包括自然因素，也存在人为因素。其中，地下管线穿越是人为引发地面塌陷的常见情形之一。在地下管线拖拉施工过程中，地质环境会发生改变，借助微动探测和地质雷达探测，能够深入分析这种施工引起的地质环境变化，并构建塌陷土体破坏模型，进而对地基的稳定性进行计算评估。对于治理地面塌陷土体，可采用高压旋喷桩进行深层加固，并在浅层设置钢筋混凝土卸荷板，这一综合措施能够有效解决地下管线穿越所导致的地面塌陷问题。更多还原

【Abstract】 Ground collapse is the result of many factors, including natural factors and human factors. Among them, underground pipeline crossing is one of the common cases of man-made ground collapse. In the process of underground pipeline dragging construction, the geological environment will change. With the help of micro motion detection and geological radar detection, we can deeply analyze the geological environment changes caused by this construction, build the collapse soil damage model, and then calculate and evaluate the stability of the foundation. For the treatment of ground collapse soil, high-pressure jet grouting piles can be used for deep reinforcement, and reinforced concrete unloading plates can be set in the shallow layer. This comprehensive measure can effectively solve the problem of ground collapse caused by underground pipeline crossing.更多还原
