Aiming at the ballasted continues welded track and turnout structure on the normal embankment, stability analysis model of continues welded track is established by finite element method to avoid the disadvantages of traditional methods, compile the finite element analysis program and make comprehensive analysis on the lateral deformation and vibrational characteristics caused by temperature force of the continues welded track and turnout str ucture.

本文针对有砟轨道普通路基上无缝线路及无缝道岔轨道结构，运用有限元法，建立了三维无缝线路稳定性分析模型，避免了传统理论假设过多的弊端，基于有限元分析软件，编写了有限元分析程序，对无缝线路和无缝道岔的横向变形和横向振动特性进行了全面研究，主要研究内容有：1。

In order to predict the post-construction settlement, based on a thorough analysis on the law of settlement development, citing the Verhulst model which good reflect its main characteristic, using the curve fitting method, mining the information contained in the construction data; betakes the improvement non-linear fitting algorithm on the model parameter inversion.

目的 为提高软土路基的工后沉降量预测精度，给设计和造价控制提供反馈信息。方法在深入分析沉降发生发展规律的基础上，引入Verhulst模型，采用改进的曲线拟合的经验计算方法，挖掘施工期的实测数据所蕴含的信息。

Construction of cement concrete pavement will be a lot of horizontal and vertical joints, in order to protect the pavement and subgrade, to extend the service life of roads, need to use joint sealant, also known as sealant or caulking adhesive.

水泥混凝土路面建设中会有很多横向和纵向的接缝，为了保护路面和路基，延长道路的使用寿命，需要用到接缝密封胶，也称为填缝胶或嵌缝胶。

In this study, two types of ground-penetrating radar systems – RAMAC and GSSI – are used for inspection. The study is carried out on the piers of an overpass in Miaoli and a factory facility in Chinning Distillery in Kinmen for investigation on the steel bars and road foundation pavement.
