摘要
随着社会的不断发展,越来越多的旧路亟待拓宽改造,如何处理新老路基的搭接,减少不均匀沉降对道路使用寿命及安全的影响成为此类工程的重点和难点。首先就旧路拓宽普遍性存在的不均匀沉降问题及产生此类病害的原因进行了简述,总结了目前旧路拓宽工程中常用的处理措施。最后结合拓宽改造工程实例,以减少不均匀沉降为目的,从加宽断面的选择及加宽部分路基处理两个方面进行了介绍。
With the continuous development of society, more and more old roads need to be widened and reconstructed. How to treat the overlap of the old and new roadbeds, and how to reduce the influence of uneven settlement on the service life and safety of road become the key points and difficulties in this kind of project. The article briefly describes the uneven settlement problems universally existing in the widening of old road and the causes of the diseases, summarizes the common treatment measures in the widening projects of old road now, and introduces the selection of widening section and the treatment of the widened roadbed in order to reduce the uneven settlement by the widening and reconstruction of engineering cases.
