基于水土保持理念的城市道路路基施工技术
|
摘要
城市道路路基施工时,常遇到路基存在深层较软弱土层需要处理且受周边生态环境限制的问题。以长安街西延道路工程为例,从水土保持角度,通过方案比选,介绍如何利用强夯法在保证道路路基稳定的同时,又能尽快恢复建设场区生态功能、利于水土保持的施工技术方法。结合具体施工实践,阐明了相关施工监控技术及水土保持评价要点。施工实践证明,此技术经济效益、社会效益良好。
The construction of the sub-grade of urban roads is often faced with such problems as there being deep weak earth layers in the process of the construction of sub-grades that have to be treated and being liable to being affected by the limits in the surrounding ecologic environment. With the Westward Extended Section of Changan Street as a practical example, the various schemes for the project are compared and the optimized one is finally chosen from the angle of soil and water conservation. Introduced in detail in the present paper are the construction techniques and methods for the construction of the project, namely, how the heavy-temping method is made use of to not only ensure the stability of the sub-grade but also restore the ecologic functions of the site field as soon as possible and help soil and water conservation. With the help of some practical examples, some of the monitoring and control techniques are dealt with in the paper, with the main important points in evaluating soil and water conservation put forward. The construction practice shows that these techniques have good economic and social benefits.
