摘要
桥头跳车妨碍道路舒适性的难题之一,从力学上分析了桥头跳车作用机理,提出桥头沉降差的控制值。研究表明台背填土沉降、桥台基础的沉降、水温、设计计算理论是导致桥头跳车的主要因素,针对性提出增加地基整体刚度及承载力、设置刚柔均匀过渡、处理好排水、改进设计计算方法等处理措施。
The bridgehead bump is one of difficulties to affect the road comfort.The article mechanically analyzes the action mechanism of bridgehead bump,and puts forward the control value of bridgehead settlement difference.The study shows that the backfill setdement,abutment foundation settlement,water temperature and design calculation theory are the main factors to cause the bridgehead bump.The article describes the treatment measures of increasing the integral rigidity and bearing capacity,setting up the rigid-flexibility homogeneous transition,treating the drainage well and improving the design calculation method.
