预留土法对高铁隧道口浅埋偏压段的影响

Three bench reservation core soil in high speed railway tunnel entrance effect of shallow bias section

在高速铁路工程的建设中,浅埋偏压隧道占据了很大的比例。随着施工技术的发展,人们研发出三台阶预留核心土法在高速铁路隧道洞口浅埋深压段施工的方法,并且取得了瞩目的效果。

In the construction of high-speed railway engineering, occupy a high proportion of shallow bias tunnel. With the development of construction technology, people has developed three steps aside core in the high-speed railway tunnel mouth method for the construction method of shallow buried depth, and remarkable results have been achieved.
