软土路基沉降及其侧向位移监控技术探讨

On Soft Soil Roadbed Settlement and Lateral Displacement Monitoring Technology

道路加宽扩建工程软基路段施工期间的稳定安全及工后沉降控制是影响施工进度和质量的关键问题。巩义境G310国道改建段软土地基路堤土地基的沉降和侧向位移直接影响到路基工程进度和实体质量,但在实际施工中,由于路基沉降观测和侧向位移观测点多、面广,观测程序繁复,加上观测过程受保通施工影响,沉降观测和侧向位移观测的正确性和准确性就难以保证。所以,我们根据规范和设计要求,按照施工现场实际情况对加宽段软土地基沉降观测的路堤填筑期、路面施工期实行有效观测和监控施工沉降观测和侧向位移观测,总结不同施工期沉降观测和侧向位移观测的监控方法。

The safety and stability during construction of road widening road expansion project soft foundation section and post-construction settlement control is the key factor affecting the construction quality and progress. In Gongyi national road G310 reconstruction section, the soft soil roadbed soil foundation settlement and lateral displacement directly affected the roadbed construction schedule and the entity quality. But in actual construction, because the roadbed settlement observation and lateral displacement observation has complex procedure, coupled with the influence of clearing construction, it is difficult to guarantee the correctness and accuracy of the settlement and lateral displacement observation. So, according to the specifications and design requirements, in accordance with the actual situation of construction site, the settlement and lateral displacement in the widen section are observed effectively and the monitoring methods of roadbed settlement and lateral displacement observation are summarized.
