在地下工程建设中,常常会遇到石灰岩溶地区的大断面隧道工程建设,不同程度工程地质问题,并且严重影响了地下工程的施工和运营安全。由于溶洞发育条件和规模的不可预见性,现场条件因地制宜的采取相应酌溶洞处理方式其处理方式也不可能千篇一律,只能结合以确保施工和工程使用安全。本文中详细的对溶洞的处理方式进行分析,并对高压灌注砂浆方式进行叙述,根据实际的工程案例来分析地下溶洞对建筑物影响进行处理,在遇到施工中的工艺问题提出相应的解决办法。
In underground engineering construction, large-section tunnel construction in limestone karst area is often encountered, and engineering geological problems of different degrees are often encountered, and construction and operation safety of underground engineering are seriously affected. Due to the unpredictability of the conditions and scale of the development of the cave, the site conditions can not be treated in the same way as the discretionary cave treatment according to the local conditions and can only be combined to ensure the safety of construction and engineering. In this paper, detailed analysis of cave treatment methods, and describes the way of high-pressure grouting mortar, according to the actual project case analysis of underground caverns to deal with the impact of the building, in the face of the construction process problems put forward corresponding solutions .
