Test method for simulating differential settlement deformation of widened roadbed
The invention discloses a test method for simulating differential settlement deformation of a widened roadbed. Comprising the following construction steps: determining alternative excavation schemes of roadbed widening steps to be compared and selected, preparing a test site, detecting a soil sample, measuring and setting out, paving soil, monitoring and measuring, determining the optimal excavation width, excavation height, geocell layer number and slope cutting rate of the roadbed widening steps, and constructing. Aiming at the problem of field test of differential settlement deformation of a road reconstruction and expansion widened roadbed, according to a road reconstruction and expansion practical project on which a project depends, in combination with related design data of roadbed filling, a corresponding field test model is established, a proper monitoring section is selected, and a certain number of monitoring equipment is arranged; and a new and old roadbed settlement curve is drawn according to monitoring data, and a proper roadbed widening and splicing scheme is selected according to a differential settlement monitoring result, so that the differential settlement of the new and old roadbed is effectively reduced.
本发明公开一种模拟拓宽路基差异沉降变形的试验方法，包括如下施工步骤：确定待比选的路基拓宽台阶开挖方案备选‑准备试验场地‑土样检测‑测量放线‑铺土‑监控量测‑确定最优的路基拓宽台阶开挖宽度、开挖高度、土工格室层数和削坡坡率‑施工，其针对公路改扩建拓宽路基差异沉降变形的现场试验问题，根据项目依托的公路改扩建实际工程，结合路基填筑相关设计资料，建立相应的现场试验模型，选择合适的监测断面，布置一定数量的监测设备，根据监测数据绘制新旧路基沉降曲线，根据差异沉降监测结果选择合适的路基拓宽拼接方案，从而有效减小新旧路基差异沉降。
