导洞法 meaning in English
pilot method
pilot tunnel method
pilot-tunneling method
pilottunnelmethod
Examples
- Based on the numerical simulation , it can be concluded that the three heading construction method with the tunnel close to the mountain tunneled first should be chosen in the construction of the multi - arch loess tunnel
计算结果表明对于偏压黄土连拱随道应采用先开挖靠山一侧的侧壁导洞法进行施工。 - Considering the actual condition of this tunnel , several key mechanical problems involved in the construction of the tunnel have been studied : the comparison of three - heading construction method and benching tunneling method , and the construction sequence of the two tunnels is carried out
本文结合该工程实际，进行黄土连拱隧道的关键施工力学问题研究：正洞上下台阶法与侧壁导洞法施工方案比较研究；先左洞（靠山一侧）施工方案和先右洞施工方案的对比。 - Then we simulate the common excavating methods of double - arc tunnel respectively , analyze the stress and strain of wall rock and support structure of each method , and recommend the best excavating method to construct double - arc tunnel in wall rocks of ii . then we analyze the " three headings method " in detail , and also simulate the effect of construction factor , stress releasing coefficient and secondary lining
对实际工程中最常用的三种开挖方法分别进行了施工模拟，分析了它们各自的围岩和支护的受力变形规律，经比较后，得出了三导洞法是类围岩中修建连拱隧道的较好开挖方法的结论。
