3 . based on the analysis of the mechanic characteristics of the earth , a concept , the magnifying effect of the subbase , was proposed to eliminate the disunity in calculations . many facts in concrete pavements can be explained by using this concept 3 、在分析土体力学性质的基础上，提出土基放大效应的概念，解决刚性路面板计算理论不统一的问题，并解释一些刚性板的工作情况。
The main contents include : 1 . the mechanics performances of geometrically similar slabs under static load on the same elastic foundation are similar , according to the analysis of slabs with similitude laws and tests of soil stress under rigid pavements with different size ratios . 2 主要内容包括： 1 、根据静力荷载下不同相似比的刚性路面板下的土压力测试结果，结合应用相似理论对弹性地基板所作的分析，指出同一场地土上几何尺寸相似的弹性地基板在静载下的力学性能相似。
Now , the scholars of internal and overseas pay close attention to the mechanics function of sfrc , such as in the references [ 3 , 13 , 14 , 16 , 23 , 27 , 28 , 29 ] , and so on . however , in the practice pavement engineering project , the sfrc is given not only the effect of vehicle and shock load , but also the effect of the temperature changes and sun radiation . therefore , the temperature and load stress are the main factor of the damage of the rigid pavement structure . because of the existent of the temperature stress , the sfrc pavement structure may be destroyed by the expand of crack . therefore , the research and analysis of the temperature load and stress of sfrc pavement structure are important to control the crack of sfrc pavement structure 目前，国内外学者对钢纤维混凝土的研究着重于钢纤维混凝土的力学性能，如文献[ 3 ， 13 ， 14 ， 16 ， 23 ， 27 ， 28 ， 29 ]等。而钢纤维混凝土在实际路面工程的应用中，不仅要受到路面车辆移动载荷和冲击载荷的作用，还要承受路表的温度变化及日辐射的作用，所以温度应力与车辆荷载应力同样都是刚性路面产生破坏的主要因素。由于温度应力的存在，会引起钢纤维混凝土路面板结构产生裂纹。
The work presented in this thesis is part of the research project - similitude laws and nondestructive diagnosis on concrete pavements , which is supported by china national science foundation . 9 slabs were tested to failure with factors of slab thickness , size ratio of geometrically similar slabs and loading place taken into account 本课题在国家自然科学基金项目“混凝土路面板相似理论与损伤诊断研究” (批准号59978015 )资助下，进行了不同厚度、不同几何相似比的9块刚性路面板的试验研究。
Linear elastic dynamic fracture mechanics are adopted to analyze the working characters of the semi - rigid asphalt pavement with the reflective cracking . it is successful to simulate the crack expansion process based on elastic damage theory , at the same time the fatigue life is forecast . the research findings are valuable for the pavement engineering practice on the soft clay ground 本文分析路表变温对软土地基上半刚性路面结构体的作用时，考虑了路表降温导致沥青混凝土回弹模量的非均匀性，采用线弹性动断裂力学分析软土地基上含反射裂缝半刚性路面结构体的工作性状。
