On basis of a review of the recent achievements , the distribution of the lateral seismic inertia force along the height of retaining wall and / or bridge abutment , and the calculation of the seismic soil pressure of cohesive backfill are treated with in this paper , for the revision of chinese earthquake resistant design code for highway construction , and a suggestion to combine sei smic design of retaining wall and of bridge abutment together into one chapter from the past in two chapters in the previous version is also worked out 结合规范jtj004 ? 89的修编，本文在总结已有研究成果的基础上，主要研究了挡土墙和桥台地震惯性力沿高度分布的规律，粘性填土的地震土压力计算和计算公式的简化，以及在公路工程抗震设计规范中将挡土墙和桥台的抗震设计归入一章的问题，具体包括如下5项工作。
Total 18 simulated acceleration time histories for intensity 6 , 7 , 8 and 9 are adopted as inputs , 6 typical retaining walls heights and 2 bridge abutments with difference are selected as the structural models of soil - structure system , the seismic responses of the system and the horizontal variation of the maximum response accelerations at different height levels are analyzed by means of a wave propagation finite element program 选用针对地震烈度6 、 7 、 8 、 9合成的总共18条地震动时程，选取具有代表性的6个不同高度的挡土墙以及2个不同高度的桥台模型，利用波动有限元法既有程序分析地震反应，研究水平地震加速度沿高度的分布规律。
And they are still difficult harness problems at present . the new concept of the fill embankment of special structure is put forward in this thesis , and it means two kinds of transitional sections of expressway - the transitional section between the fill embankment behind bridge abutment and a bridge , and the transitional section between the slope after excavation and the fill embankment along one side of it 论文针对这两类公路病害，以广东省粤肇高速公路的工程建设为依托工程，提出了“特殊结构的填土路堤”的新概念，它指的是路桥过渡路段和填挖过渡路段，并在此认识的基础上，深入地探讨了台背填土路堤和半填半挖路基的变形特性及相关的公路病害问题。
The results indicate that this method can minish settlement largely , decrease level thrusts on bridge abutment , make the settlements transition , improve the bearing capacity of foundation soil and its economic benefits are notable . the results of field test show that low intensity piles can put into widely use in soft foundation of express way 研究结果表明，采用低强度桩复合地基加固桥头软基时，可以采用变桩长、变间距的设计思想，使沉降逐渐过渡，减轻桥头跳车的危害，并且还可以减小沉降和深层土体水平位移，减小对桥台及其桩基的水平推力，提高地基承载力。
Abstract : through the theoretical liquid dynamics complex study to the bridge pier and abutment circling flow , this paper related with bridge abutment maximum clear water equilibrium scouring experiment ? s analyses has made out the bridge abutment ? s velocity circulation , maximum flow capacity per unit width , and the maximum part scouring depth counting method 文摘:对不可压缩理想流体桥台平面绕流复势研究，确定桥台绕流流速环量和桥台极限绕流流量，并结合清水极限平衡冲刷实验进行桥台最大局部冲刷深度的理论探讨
The research pays attention to the settlement patterns of the fill embankment behind bridge abutment for vehicle bump at bridge - head , and the formation reasons of it and the behavior and mechanism of reinforced roadbed consisting of the slope after excavation , the fill embankment and geogrid under loads are analyzed for the fill and excavation roadbed problem 对于桥头跳车问题着眼于台背填土路堤的沉降规律的研究，对于填挖交界问题则主要针对病害的形成成因和采用土工格栅处治的加筋机理及其效果的研究。
