加固边坡稳定性监测技术的研究及工程应用

Research on Technology of Stability Monitoring of Reinforced Slope and Engineering Application

现场监测是预测边坡发展趋势的一种十分有效的方法。由此,对边坡稳定性监测技术进行了研究。针对不同情况加固边坡的监测,建立了一套监测流程模式,归纳了边坡稳定性监测的目的、原则和内容,对边坡监测断面、点和网的布置,以及近年来的监测方法及监测仪器设备进行了总结和分类。通过研究,认为根据一定原则建立起的以位移变形监测为主的立体监测网是监测方案的根本。最后结合工程实例(常德～吉首高速公路K196+755～K197+180段的朱雀洞滑坡),将监测技术应用于加固边坡,以观察加固方案对边坡所起到的稳定作用。

On-site monitoring for predicting development trend of slope is a very effective way, thus stability monitoring techniques of slope are studied. For monitoring different situations reinforced slope, a monitoring process model is established, purposes, principles and content of stability monitoring of slope are summed up, and layout of monitoring sections, point and network of slope, as well as monitoring methods and monitoring equipments of recent years are summarized and classified. Through researching, it shows that it is basic of monitoring program that three-dimensional monitoring network is built on main of monitoring of displacement and deformation according to certain principles. Last, with engineering exam- ple （Zhuquedong landslide, lied on section of K196 q-755 ~ K197 ＋ 180 of Changde-Jishou Expressway）, monitoring techniques are applied to reinforced slope, in order to servey that reinforcement program played a stabilizing effect on the slope.
