According to the different thermal fields and the maximum thermal gradient , the thermal stress of lean concrete base with asphalt surface can be calculated through fem , and the formula of calculating thermal stress for lean concrete base with asphalt surface is also brought forward based on that 根据不同自然区划的温度场和最大温度梯度，得出贫混凝土基层沥青路面中的基层温度应力的有限元解，于此提出了基层温度应力的计算公式。
In this part , it demonstrates with sufficient argumenls in the aspects of material choice for the surface course , base course style , road drainage , etc . in theory it solves the troubles in the weak surface course , the weak base , the poor road drainage , etc . the thesis also debates on the exploration of constructive technique on the method of design of the cement concrete pavement based on the poor concrete base 本文首先分析了宣大高速公路交通组成，介绍了我国几个水泥混凝土路面建设大省的经验，总结了国内外水泥混凝土路面的研究成果，从面层选材、基层类型与排水等方面都作了详细论证，从理论上解决了面板薄、基础弱、排水差等问题。本文对贫混凝土基层水泥混凝土路面的设计方法也进行了有益的探索。
In order to analyze the base stress of such a new type pavement whichasphalt surface goes upon lean concrete base , calculating the load stress without asphalt surface through fem firstly , and then analyzing the effecting of asphalt surface ' s thickness based upon elasticity theory , and finally the formula of calculating load stress of lean concrete base with asphalt surface worked out according to the previous data 摘要为分析贫混凝土基层沥青路面新型路面结构的基层应力情况，通过有限元分析方法计算贫混凝土基层的荷载应力，并利用弹性层状体系理论分析沥青面层厚度对其影响，由此推导出基层荷载应力的计算公式。
3 . based on the bond test for 33 concrete specimens and gfrp and bending test for 15 beams strengthening with gfrp , surface preparation of concrete , type of epoxy adhesives , thickness of adhesives , hardening time of adhesives , cure condition after strengthening are considered , and the effect on concrete structures strengthening with gfrp causing by construction behavior was analyzed . 4 根据gfrp片材加固混凝土结构在施工中常涉及到的一些相关因素，如混凝土基层表面处理情况、所选用的粘结剂类型、涂抹粘结剂的厚度、加固的方式以及养护状况，进行了33个混凝土试件与gfrp片材的剪切粘结试验，并进行了采用gfrp片材加固的15根混凝土梁的抗弯试验，分析了与施工性能相关的因素对gfrp片材加固混凝土结构效果的影响。
