查询词典 tensile stress

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.

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。
