复杂条件下隧道施工中的超前地质预报方法研究

超前地质预报在复杂的地质条件下对隧道工程的施工及施工安全起着非常重要的作用。通过地质超前预报,及时发现异常情况,预报掌子面前方不良地质体的位置、产状、含水情况及围岩结构的完整性,从而为优化隧道施工方案提供依据,为预防本隧道突水、突泥等可能形成的灾害性事故及时提供信息,在施工前做好准备,避免损失。超前地质预报可以更准确地确定不良地质的性质、种类、位置和规模,以及围岩的级别。超前地质预报对于隧道,特别是地质条件复杂、工期紧的隧道快速、安全施工来说,其作用和意义尤为突出。

Advance geological forecast in tunnel construction under the condition of complex method research

Advanced geological forecast plays a very impor-tant role in the complex geological conditions of tunnel engineer-ing construction and construction safety. Through the geological advanced prediction, people can find the abnormal situation in time, forecast constraints in front of the adverse geological loca-tion, occurrence, water cut and the integrity of the structure of surrounding rock, so as to provide basis for the optimization of the tunnel construction scheme, in order to prevent the tunnel water inrush, sudden mud, etc. and to prepare before the con-struction, which can avoid the loss. Advanced geological fore-cast can more accurately determine the nature of the bad geolog-ical, type, location and size, as well as the level of the sur-rounding rock. Advanced geological forecast plays an important role for tunnel, especially in complicated geological conditions, the tight for fast, safe construction of tunnel.
