Abstract

With the rapid development of urban economy and the rapid growth of traffic volume. The traffic pressure on roads is becoming more and more severe. It is necessary to rebuild or expand the existing roads to meet the increasing demand of traffic and transportation. However, there are some problems in the widening of the existing retaining wall section, such as high probability of damage and difficult reuse of retaining wall. In order to solve these problems, this paper starts from the aspects of reducing the earth pressure of retaining wall, reducing the probability of road damage and imp roving the integrity of structure. A road widening structure is designed. The analysis shows that the structure can meet the requirement of retaining and widening the existing retaining wall. And it can also control the problem of uneven settlement at the junction of old and new roads; From the point of view of construction technology, the study of the structure of the site construction efficiency is high and its site practicability is strong.
