| 摘 要： | 城市建筑垃圾在城市发展建设过程中增加了城市环境保护管理的难度,同时加速了对土石资源的消耗。为协调城市建设与城市建筑垃圾之间的矛盾,研究提出以建筑碎石作为建筑再生料,并应用于城市道路建设工程中。结合上海S7公路(月罗公路—宝钱公路)新建工程,介绍建筑碎石在"永临结合"施工便道中的施工工艺、填筑方案及质量验收情况,充分论证了建筑碎石循环利用于道路路基工程中的可行性,为处理城市固体废弃物提供了一个极具应用价值的新思路。

| Abstract: | A seawall in shanghai is located above the tunnel. Because of the seepage failure and seawall soil erosion, the slope is collapsed and the barrier board is suspended in air and is broken. It is urgently to maintain and reinforce the seawall. In order to insure the construction safety, FLAC3D numerical modeling method is used to calculate the influence of seawall reinforcement and maintenance on the lower tunnel displacement. The calculation is divided into two processes of riprap construction and high-pressure jet grouting pile construction. The calculation result shows that the influence of engineering practice on the tunnel is controllable. |
