软土路基沉降观测方法探讨

Study on Settlement Observation Method of Soft Soil Subgrade

公路线路经过软土路基时会出现明显的不均匀沉降,其在设计和施工中的沉降分析和计算结果精度不足以满足无工后沉降的要求,需要对沉降进行实时观测和分析。以软土地基上某公路工程施工中的沉降观测为例,介绍公路线路中路基沉降观测的流程、元器件的埋设方法,总结了沉降观测过程中各类元器件的适用性,及真实、准确、及时和连续采集沉降观测数据的方法,为以后类似工程的沉降观测提供参考。

There will be obvious uneven settlement when road passes by the soft soil foundation.Settlement analysis and calculation results precision during design and construction cannot meet the requirement that no settlement after project is finished.So the settlement needs to be real-time observed and analyzed.Taking the settlement observation of road construction on soft soil foundation as example,the process of subgrade settlement observation and burying method of components are introduced,the adaptability of components and the method of collecting settlement observation data factually,exactly and betimes are summarized,which will provide reference for settlement observation of similar engineering.
