随着我国社会的迅速发展,部分公路功能已不能满足日渐增长的交通需要,特别是二级公路在运营中表现出严重的不适应发展要求,路面病害迅速增加,交通事故频频发生,因此对二级公路进行加宽改造势在必行。通过对某二级公路加宽工程设计进行分析,指出了在公路加宽设计中应注意的问题,以期对以后的公路加宽工程设计起到借鉴的作用。
With the rapid development of our society, some of the functions of the highways can no longer meet the growing traffic needs. In particular, the secondary roads show serious unmanageable requirements during operation. Pavement diseases are rapidly increasing and traffic accidents occur frequently. Therefore, Highway widening transformation is imperative. Through analyzing the design of a second-class highway widening project, the problems that should be paid attention to in widening the highway design are pointed out, with a view to reference the future highway widening project design.
