摘要
结合工程养护经验,在原有评定方法以沉降差为依据的基础上,引入了桥头跳车影响长度L以及桥头跳车影响面积S。对桥头跳车常用维修方案进行了比较,其中沥青层铣刨加铺方案通常采用维修范围起点与桥台标高控制,与拟合最优标高存在一定偏差值,同时对偏差值进行了研究。
Combined with the engineering maintenance experience,on the basis of the existing assessment method based on settlement difference,this paper introduces the influence vehicle jumping length L and vehicle jumping influence area S of bridgehead. Commonly used maintenance schemes of the vehicle jumping at bridgehead are compared,and milling planer asphalt layer overlay scheme usually uses the maintenance scope starting point and the abutment elevation control. There is a certain deviation with the optimal elevation fitting values,and the deviation value is studied.
