【摘要】：在高速公路加宽工程中采用"水平向加筋+竖向增强体"的桩网复合地基处理技术,并应用有限元软件进行模拟分析。研究表明:桩网复合地基处理技术解决了施工中新老路基沉降差异和路堤拼接质量的问题,新老路基之间竖向产生的差异沉降和新路堤水平位移都得到有效地控制,能够满足高速公路扩建的要求。
[Abstract]:In the highway widening project, the "horizontal reinforcement + vertical reinforcement"-based composite foundation treatment technology is adopted, and the simulation analysis is carried out by using the finite element software. The research shows that the pile-net composite foundation treatment technology solves the problem of the settlement difference of the new and old subgrade in the construction and the quality of the joint of the embankment, and the differential settlement of the vertical generation and the horizontal displacement of the new embankment between the new and old subgrade are effectively controlled, and the requirements of the extension of the expressway can be met.
