Large numbers of test data which is systemic, credible, exact and detailed was acquired during the processing of these two scientific research item and settlement value and theoretical analysis on trial section was done together with the test and research on the site. The connection between the rule of settlement in the transition zone and the parameter such as groundsill, transmogrification modulus, material and density was studied based on comparing true settlement value in trial section with settlement value of theoretical calculation by frame analysis software. And it will help the farther research on design and construction about road-bridge transition zone.

同时在两个科研项目开展过程中，取得了大量系统、详实、可靠的试验数据，并结合现场试验研究工作，在室内开展了深入细致的过渡段沉降变形数值计算和理论分析研究，运用有限元分析软件，对过渡段的沉降变形进行了仿真数值模拟计算，与现场实测数据进行了对比分析，全面考察了过渡段地基土层与变形模量、路堤填料与压实密度等参数对过渡段沉降变形的影响规律，为进一步研究路桥过渡段的设计和施工可以提供借鉴。

The section of the embankment model was symmetric trapezium and the clay was its filling.

路堤模型采用梯形对称截面，并以粘土作为填料制作。

For the structural design parameters of flat - slab beamless pile structure which can be directly used for the low embankment of soft weak subgrade of passenger dedicated line, the analyses are made for the all performance indexes of the structure under the static and dynamic conditions by using a space calculation model.

研究方法：根据相关规范和规定，分析了既有特殊路基和桥梁结构工程，研究了各种构造的优缺点，针对客专拟定可直接用于工程的软弱地基低矮路堤的无梁板式桩柱结构设计参数，采用空间计算模型分析该结构在静力和动力情况下的各项性能指标。

Research purposes:Through doing overall researches,it is proposed to adopt flat-slab beamless pile structure for low embankment of soft weak subgrade,which can be suitable for ballast and ballsatless tracks and control the structure s settlement with easy construction and low construction cost.

研究目的：通过全面研究，提出软弱地基低矮路堤采用无梁板桩柱结构，保证结构可适应有碴及无碴轨道，达到结构沉降可控，施工方便，造价经济的目的。

Research conclusions: As a structure of low embankment of soft weak subgrade, beamless slab can satisfy the requirements of ballast and ballastless tracks and can control the structure＇s settlement.

研究结论：无梁板桩柱作为软弱地基低矮路堤结构可以满足有碴或无碴轨道结构的要求，工程沉降达到可控，技术成熟，施工不必碾压路基，简化了施工环节，方便、环保、节约土地，它的推广应用必将具有良好的社会及经济效益。

Therefore,test and research on subgrade treatment of cataclastic expansive rock,retaining and protection of high cut slope in crushing and weak rock,and new retaining structure types of high embankment slope,such as piles-plate wall of prestressed anchor wire,reinforced earth retaining wall of new type straps,are conduc.

对此，开展了碎裂膨胀岩路基边坡处理、破碎软岩路堑高边坡挡护和路堤高边坡新型支挡结构(锚拉式桩板墙，新型拉筋加筋土挡土墙)等项结合工程的科研试验，取得突出成果，为南昆铁路的顺利建成和安全运营提供了科学依据。

In the practice we have no special design of the approach slap , and the theoretical thereunder is not so reasonable. For example, when calculate the length of the approach slap, we adopt the permission differential change slap and settlement, without considering the height of road embankment filling , the form of abutment and the properties of the filling sort, so sometimes it is hard to eliminate the bridge head bump completely because of the disjoint, rupture or overshort of the approach slap, influencing the use of the road and bridge.

实践中一般桥头搭板不作专项设计，且理论依据不甚合理，如搭板长度计算采用桥头容许变坡差和沉降量确定，没有考虑路堤填土高度、桥台形式及填土性质，所以有时会出现搭板脱空、断裂或过短而未能彻底消除跳车现象，从而给道路桥梁的使用带来影响。
