摘要
针对公路高边坡的不稳定性,论文采用无线测距定位技术,设计了抛洒式位移监测系统进行滑坡监测。其中,针对抛洒式观测站的位置,采用非线性最小二乘法进行估计,并利用DOP值评估了试验场地的观测站测量精度。利用南京汤山镇的一处人工渣土山进行了试验,采用底部开挖的形式形成人工滑坡,并利用文中提出的系统进行滑坡监测,得到了良好的结果。此系统可为公路高边坡的稳定性监测提供一定的参考。
In regards with the instability of highway high slope,this paper adopts wireless ranging technology,and the throwing type displacement monitoring system is designed for landslide monitoring.The position of throwing type observation station is estimated by the nonlinear least square method,and the accuracy of observation station is evaluated by DOP.Experiments are carried out by an artificial slag soil in Tangshan Town of Nanjing,and artificial landslide is formed by bottom excavation,landslide monitoring is carried out by using the system proposed in this paper and good results are obtained.This system can provide important reference for the stability monitoring for high slope of highway.
