摘要:
为了消除强夯模型试验箱壁无法避免的边界效应,设计了一种操作简易、成本低廉的强夯模型试验装置.首先简要介绍了该试验装置的设计思路及制作过程,并对该装置的试验操作过程进行说明.然后利用该简易装置进行强夯模型试验,在相似定理的基础上,通过量纲分析对试验数据中的夯坑深度进行研究分析,建立了无量纲夯坑深度与土质参数和施工工艺参数无量纲量间的相关方程.最后将该夯坑深度估算方程计算出的夯坑深度值与几例工程实测深度数据进行对比验证,结果表明两者具有很好的一致性,说明该方程可用于推算现场强夯时的夯坑深度.通过研究可知该简易装置具有一定的实用性,能满足工程现场夯坑深度的估算
Abstract:
In order to eliminate the inevitable boundary effect of the box wall in the dynamic compaction model test, a new type of simple-operation and low-cost device was developed. Firstly, the design mentality and manufacture process of the test device were introduced briefly, which was followed by the illustration of operation process of test device. Secondly, based on the similarity theorem, the dynamic compaction model test was carried out with this simple device, and the test data of the crater depth was studied according to the dimensional analysis, from which a relevant equation was established among the dimensionless of crater depth and soil conditions parameter and construction process parameter. Finally the results were compared between the crater depth of equation calculating and real-test data of some projects, which showed a good consistency. It is indicated that this simple device has certain practicability when applied to the estimate of the crater depth in practical engineering.
