悬索桥锚碇模型试验中水的弱化作用试验分析

Experimental Analysis on Weakening Action of Groundwater in Model Tests for the Anchorage of Suspension Bridge

以宁波庆丰大桥锚碇模型试验为例,通过室内单向压缩试验和直剪试验,得出了饱水模型砂和相对干燥模型砂的压缩模量和抗剪强度折减系数,从而对模型试验所得的结果进行了修正,使试验结果更加符合实际工况,为锚碇设计提供了依据。

Based on the model test of the anchorage of Qing Feng Bridge in Zhejiang Province,the reduction coefficients of compressibility modulus and the shear strength for the saturated model sand compared with the dried model sand are obtained from the simple compression tests and the direct shear tests.The results from the model tests are modified by using the coefficients,which makes the results are more fit for the practical situation.
