【摘要】 隧洞施工的主要施工方法是传统的钻爆法和现代的掘进机法,各个方法均有其不同的适用条件。在长大深埋隧洞施工中,由于洞线长,涉及的围岩种类繁多,岩石强度及破碎程度不同,且埋深不一,采用单一的施工方法可能很难满足施工的需要。文中通过辽宁省大伙房水库输水工程建设实例,分别论述了复杂地质段和单一地质条件施工方法的选择,供今后类似工程参考。更多还原

【Abstract】 The main methods for the construction of tunnel are usually both the traditional drilling and blasting method and the modern method of TBM, which have their own applicable conditions concerned. During the construction of a deep-embedded tunnel with long distance and large cross-section, only one tunneling method is hard to meet the construction requirement as the tunnel line is too long with varied embed depths, and furthermore, different classes of surrounding rocks with various strengths, breaking degrees are to be met therein. Based on the construction practice of the water conveyance project of Dahuofang Reservoir in Liaoning Province, the selection of the construction method for both the complicated geological condition and the uniform geological condition is discussed herein, so as to provide a reference for the other similar projects.更多还原
