摘要
在深地下工程施工过程中,各种不良地质常成为制约深地下工程修建的主要因素.超前地质预报是地下工程探查掌子面前方不良地质、降低施工风险的一项重要技术措施.在深入分析常用地质预报方法特点基础上,提出深地下工程综合超前地质预报技术体系.以某深地下工程为例,采用地质调查法+TSP+地质雷达法+红外探水综合超前预报方法开展实际工程应用,并对复杂含水地带进行超前钻探验证.工程应用实践表明,预报结果与开挖揭露情况吻合较好,该综合超前地质预报技术可为深地下工程施工安全提供技术支撑.
In the process of deep underground engineering construction, various unfavorable geological conditions are the factors that affect such constructions. Advanced geological prediction is an important method to explore those conditions in front of tunnel face and reduce construction risks. Based on the in-depth analysis of features in commonly used methods for geological prediction, this paper proposes a comprehensive geological prediction technique system of deep underground constructions. Taking a deep underground engineering as an example, actual engineering applications are carried out by using the comprehensive geological prediction method of ＂ geological survey ＋ TSP ＋ ground penetrating radar ＋ infrared water detecting＂. And complex water areas are verified by advanced drilling. The engineering practice shows that the prediction result is consistent with the excavated situation, and this technology is of great value to the construction safety of deep underground engineering constructions.
