高深路堑开挖监控量测施工技术研究

由于高深路堑开挖施工地质复杂,现场机械及人员较多,而有效的监控量测对于调控施工进度,判断边坡的稳定状态以及指导现场施工等发挥着重要作用。为更好的了解边坡动态,更为准确、详细可靠的分析边坡情况,确保施工安全,本文以某公路边坡为工程背景,以现场监控量测为手段,对不同时间、机械开挖不同位置以及降雨前后的边坡进行动态观测。结果表明,位移量随着时间的增长而逐渐减少,反弯点出现后边坡逐渐趋于稳定状态;边坡累计沉降量随开挖深度的增加而不断上升,最后趋于稳定状态。

Research on Construction Technology of Monitoring and Measurement for Excavation of High and Deep Cutting

Due to the complex geology of the high-deep cutting excavation and the large number of on-site machinery and personnel,effective monitoring and measurement play an important role in regulating the construction progress,judging the stability of the slope and guiding the on-site construction.In order to better understand the slope dynamics,analyze the slope conditions more accurately,in detail and reliably,and ensure construction safety,this article takes a highway slope as the engineering background,and uses on-site monitoring and measurement as a means to conduct mechanical excavation at different times and Dynamic observation of slopes at different locations and before and after rainfall.The results show that the amount of displacement gradually decreases with the increase of time,and the slope gradually tends to a stable state after the emergence of the inverted point;the cumulative settlement of the slope increases with the increase of the excavation depth,and finally tends to a stable state.
