徐州高铁站区邱山及凤凰山填方山体变形监测分析

Analysis on Mountain Deformation Monitoring of Qiu Mountain and Fenghuang Mountain Fill at Xuzhou High-speed Railway Station Area

阐述了徐州高铁站区邱山、凤凰山填方山体变形监测的内容、方法及监测点的布设方案.自2010年8月20日至2011年10月25日,对两山填方山体进行了水平位移、垂直位移和地表裂缝观测,并对监测结果进行分析,认为虽然近年山体变形有所减缓,但是平均每个监测点的沉降速度仍达0.044mm/d,填方山体还处于不断变形的阶段,需要继续加强监测.

This paper expounds the contents and methods of mountain deformation monitoring of Qiu Mountain and Fenghuang Mountain fill at Xuzhou high-speed railway station area,as well as the layout scheme of monitoring point.From August 20th of 2010 to October 25th of 2011,we carried out horizontal displacement monitoring,vertical displacement monitoring and surface crack observation of the two mountain fill,as well as analysis on the monitoring results.The results show that the settling velocity reaches 0.044m/d in spite of the mountain deformation＇s slowdown these years.The fill mountains are still in the stage of deformation and the monitoring needs to be strengthened continuously.
