桥头跳车问题一直是困扰桥梁工程技术人员的难题之一,产生的根本原因是构造物与其两端接线路堤间的沉降差,事实上完全消灭沉降差几乎是不可能的,我们采取防治措施的目的是减少沉降差,使其控制在设计行车速度下,以满足使用要求。沉降差产生的主要原因1.桥头路堤及锥坡范围内地基处理不 The problem of bridgehead jumping has always been one of the difficult problems for bridge engineers and technicians. The root cause is the poor settlement between the structure and the embankment at both ends. In fact, it is almost impossible to completely eliminate the difference of settlement, and we take preventive and control measures The purpose is to reduce the difference in settlement, to control the design speed, to meet the requirements. Subsidence caused by the main reasons for 1. Bridgehead embankment and cone slope within the scope of treatment is not
