| 摘 要： | 目前有关碎石桩复合地基在动荷载作用下的研究主要是针对其排水作用,而对其密实作用的研究很少,碎石桩复合地基在动荷载作用下沉降计算理论落后于工程实践.为了在碎石桩复合地基的动力模拟试验中模拟碎石桩的密实作用,设计了大型堆叠式剪切模型箱,并采用振动沉管法在振动台模型箱中进行了碎石桩的震后沉降试验研究,结果表明其能较好地模拟碎石桩振动沉管施工工艺.

| Abstract: | The research of stone pile composite foundation under dynamic load concentrates mainly on its drainage but not on its compactness effects.This makes that research of composite foundation settlement by dynamic load is behind its engineering practice.We designed a laminar shear model box for simulating the compactness of stone pile composite foundation,and through vibration sinking pipe stone pile technology,carried out a large-scale shaking table test to research post-earthquake settlement behaviors of stone pile composite foundation.The results show that the test is succesful in simulating construction technology of vibration sinking pipe of stone pile. |
