| 摘 要： | 通过对高填土路堤这类柔性基础下桩土类复合地基进行室内砂箱模型试验研究,采用砂性土模拟软土地基,掺入适量水泥的人工拌和土模拟路堤填土.考虑平面应变特性及群桩效应,选择填土路堤下连续布置的三排桩按照一定的比例关系加工试验模型,通过百分表记录荷载板的P-S曲线,采用布置砂线和埋设位移观测点的方式观测复合地基在不同荷载条件下的位移场,从复合地基沉降和变形的角度对柔性基础复合地基的一些特性进行初步的定性分析,找出其中的某些规律. |

| Abstract: | A simple laboratory model experiment about composite ground under flexible foundation has been done.Soil is used to simulate the soft ground and clay mixed with some cements used to simulate the embankment.Taking the plane strain characteristics and the pile group effect into consideration,the experimental model can be gained by means of the three rows of piles continuously distributing under the flexible embankment.The P-S Curve is recorded by the extensometer and the displacement field of the composite ground is also gained by the soil line and the displacement observing points.Some qualitative analysis from the point of the settlement and deformation about the composite ground under flexible foundation is executed and some regularity is obtained in this paper. |
| Keywords: | flexible ground model experiment settlement deformation |
