Abstract
In order to ensure the safety of high slope construction and operation of mountain highways,combined with the G342 highway reconstruction project,a sensitive,efficient and targeted high slope monitoring plan was devel-oped by a monitoring method combining GNSS with traditional geodetic surveying and representative monitoring points.At the same time,GNSS,a monitoring and warning system for mountain high slopes was constructed by static level and series inclinometer.Through the analysis and research of real-time monitoring data of surface displace-ment,deep displacement and surface settlement,it can be concluded that there is no significant change in horizontal surface displacement,while vertical one decreases with the increase of slope elevation.The sliding section of the slope was above the second level platform;The cumulative deformation of deep horizontal displacement was gener-ally within a controllable range and had relatively better stability;Within a depth range of 9～11 meters from the first level platform,there was a sliding surface of the slope.So it was the focus of later slope monitoring.The rein-forcement and protection were strengthened in the area;Surface subsidence had the highest rate of change in early stage,and the relative subsidence height was also relatively larger.Over time,the subsidence changes gradually slew down and the subsidence amount gradually stabilized.In addition,the middle position of the high slope was relatively closer to the predicted slip zone.Compared with the two sides,the settlement change in the middle position was relatively larger,but the whole settlement was within a controllable range.关键词
