| 摘 要： | 为了研究降雨对边坡变形和监测点布置的影响,运用有限差分-强度折减法计算边坡在不同折减系数及降雨强度下的变形,通过灰色理论分析获得边坡拟监测点变形与折减系数的关联度,实现边坡变形监测布置优化,并结合实际工程制订监测点优化布置方案。结果表明:降雨作用更易导致边坡发生浅层破坏;灰色关联度应用于工程中监测点的布设,避开了不必要的监测点,使得监测数据更有利于指导预警工作。

| Abstract: | In order to study the influence of rainfall on slope deformation and monitoring point arrangement, the finite difference-strength reduction method was used to calculate slope deformation under different reduction coefficients and rainfall intensity. The correlation degree between deformation of monitoring points and reduction coefficient can be obtained by using grey theory analysis, which can realize the optimization of slope deformation monitoring arrangement, and a monitoring point optimization arrangement plan was formulated according to an actual project. The results show that the slope is more possible to behave shallow failure due to rainfall. The application of grey relational degree in engineering can avoid the unnecessary monitoring points and make the monitoring data more conducive to guiding the warning work. |
