以杨春湖隧道基坑开挖为实例,通过数值模拟的方法,得出开挖后土层水平位移等值线图,并对所得到的数据进行分析,得出基坑开挖后的位移变化规律。根据施工现场的情况和位移变化规律,对基坑边坡选取喷锚或喷网水泥浆支护。
以楊春湖隧道基坑開挖為實例,通過數值模擬的方法,得齣開挖後土層水平位移等值線圖,併對所得到的數據進行分析,得齣基坑開挖後的位移變化規律。根據施工現場的情況和位移變化規律,對基坑邊坡選取噴錨或噴網水泥漿支護。

Taking the foundation trench excavation of Yangchun Lake tunnel as example,through numerical simulation method,it obtains soil stress distribution after foundation trench excavation and the horizontal displacement contour maps of slope and then gets displacement variation after foundation trench excavation according to the data analysis.Foundation trench slope will be reinforced by anchorage and shotcrete support or Netting Structures according to the conditions of construction site and displacement variation.
