摘要
根据国内外文献资料,主要就地震高烈度区液化引起的地面侧向大变形对桥梁桩基的影响的研究现状进行分析,总结了地面大变形引起的震害情况、液化诱发地面大变形的机理及液化大变形的预测方法、桥梁桩基的震害和液化大变形对桥梁桩基的影响、桥梁桩基抗地面大变形的措施,以及存在问题和研究思路。
In this paper, on the basis of many studies reported in the literature, the effects on bridge pilesare reviewed of the liquefaction induced lateral spread and large ground displacements. This study involvesinvestigation of earthquake damage, the mechanism for the lateral spread and large ground displacementinduced by earthquake and the associated evaluation method, investigation of bridge pile's damage inducedby earthquake and summary of effects on bridge piles of the lateral spread and large ground displacement.Some measures of ground improvements are suggested against lateral spread and large ground displace-ment.
