摘要:
为了保证开挖边坡时的施工安全,针对新加坡·南京生态科技岛河道整治工程特点,提出相应清淤方法及施工流程,设计边坡分层开挖方案,建立边坡开挖计算模型,提出边坡动态安全系数跟踪计算方法,进行施工期边坡安全稳定控制。研究发现,边坡实际开挖量占总开挖量的30%及60%时,边坡安全系数降至1.15以下,及时调整施工方案后安全系数均有不同程度提升,以保证施工过程中不出现边坡失稳问题。为施工期边坡稳定动态分析提供新的参考思路。
Abstract:
In order to ensure the construction safety, when the excavation slope based on Singapore, Nanjing ecological characteristics of island in the river regulation project of science and technology, the corresponding method of dredging and construction process was put forward, layered slope excavation plan was designed, a calculation model of slope excavation was established, the slope dynamic safety factor tracking calculation method was put forward, so as to analyze the security and stability of slope during the construction. It's found that when the actual excavation amount of the slope accounts was 30% and 60% of the total excavation amount, the slope safety factor dropped below 1.15. After timely adjustment of the construction plan, the safety factor increased to varying degrees to ensure that no slope instability occurred in the construction process, which provided a new reference idea for slope stability dynamic analysis during construction period.
