Again, I maintain that we should use the flexural-tensile strain and the vertical shearing stress of the bottom of cover of the joint as the target for the design of the cover structure of asphalt on the old cement concrete. In addition, on the basis of much theoretical analysis, I preliminarily put forward to a designing methods to anchor the old cement concrete road by using dog irons made of iron bars and then covering it using asphalt concrete structure. Finally, through selecting the plan of the cover of the road to be experimented, and making a detailed introduction to the techniques of construction according to the result of theoretical analysis, I know that after anchoring the slabs close to each other with dog irons made of iron, and then cover them using asphalt cement concrete has an obvious effect on preventing and slowing down the reflection cracks in the bituminous concrete skin coat over the old road.

在大量分析的基础上提出了马钉锚固罩面结构中相邻两块水泥混凝土板接缝处的相对水平位移、相对垂直位移、接缝处沥青层底部的弯拉应变和剪应变的计算公式；再次，提出了采用接缝处罩面层底部的弯拉应变、垂直剪应变作为旧水泥混凝土路面上沥青混凝土罩面结构的设计指标，并在大量理论分析的基础上，初步提出了马钉锚固旧水泥混凝土板后沥青混凝土罩面结构的设计方法；最后，根据理论分析的结果，选定试验路的罩面方案，并对其施工工艺进行了详细的介绍，表明采用钢筋马钉锚固相邻混凝土板后，再进行沥青混凝土罩面的方法在防止或减缓罩面层反射裂缝方面具有明显的效果。

It mainly contains the following things. At first, I bring for the way of anchoring two cementing slabs next to by using dog irons made of iron bars and then cover the surface of the road using bituminous concrete. After analyzing the feasibility of this method by using the famous and popular use soft ware ASYS, the results show the magnitude of the temperature stresses on the limited mat coat of the road has nothing to do with the length of the concrete slabs after covering it with bituminous concrete. Meanwhile, the relative horizontal shifting, the flexural-tensile strain, and the vertical shearing stress of the slabs next to it becomes the least after anchoring them with dog irons made of iron. Therefore it proves that it really works to use this method to prevent and slow down the speed of the reflection cracks in the bituminous concrete skin coat over the old road.

首先，提出采用钢筋马钉锚固相邻水泥混凝土板后再进行沥青混凝土罩面的新方法；采用国际著名的通用有限元软件ANSYS对其可行性进行了分析，结果表明在有限尺寸的板上进行沥青混凝土罩面后，罩面结构的温度应力的大小与板的长度几乎没有关系，同时采用钢筋马钉锚固相邻旧水泥混凝土板后，可以明显地减小相邻板的相对水平位移、接缝处罩面层底部的弯拉应变和垂直剪应变，从而表明该法对防止或减缓旧水泥混凝土路面上沥青混凝土罩面层的反射裂缝是确实可行的。

Thin elastic foundation of cement concrete pavement design theory, in-depth analysis is to arrive at the grass-roots non-uniform bearing broken concrete pavement panels, gnawing edge, the wrong units, as well as the main reason for structural damage produced by taking certain measures to improve the concrete between the road surface and the grass-roots support conditions, and improve durability of the cement concrete pavement and stability.

通过水泥混凝土路面弹性地基薄板的设计理论，深入分析得出基层的不均匀支承是水泥混凝土路面断板、啃边、错台、以及产生结构性破坏的主要原因，通过采取一定措施改善砼路面面层与基层之间支撑条件，提高了水泥混凝土路面的耐久性和稳定性。

The oid in the cement as seen in both the kyphoplasty sections (Figure 5) is caused by the filling deice, which is left in place in the caity during the initial curing phase of the cement to preent cement from leaking back into the working cannulas.

在两个后凸成形术组中，都可以见到由填充装置引起的骨水泥间隙，这是在骨水泥凝固的初始阶段，为了防止骨水泥渗漏进工作套管，而适当地遗留在空腔中的。
