地下水封石洞油库岩爆灾害预测评估——以某地下水封石洞油库实际工程为例

地下水封石洞油库属于大型地下工程,岩爆灾害是施工过程中可能引发的地质灾害之一。本文以某地下水封石洞油库实际为例,介绍了建设场地地质灾害危险性评估中岩爆灾害预测方法。借鉴目前国内外岩爆判别的主要方法,并依据拟建工程场地实际情况,选用岩体初始应力及岩石单轴抗压强度作为定量评估指标,对岩爆灾害进行预测评估。根据宏观分析与定量评价结合的方法最终确定岩爆灾害程度。

PREDICTION AND EVALUATION OF ROCKBURST DURING THE EXCAVATION OF THE UMDERGROUND WATER-SEALED OIL SATORAGE CAVE--TAKING ONE OF OIL STORAGE CAVES IN SHANDONG PROVINCE FOR EXAMPLE

Underground water-sealed oil storage cave is a large scale underground project, and rockburst is one of the geologic hazards that will possibly occur during the excavation of the cave. Taking one of oil storage caves in Shandong for example, this paper illustrates the prediction procedure of rockburst in the geologic evaluation of the project location. Referring the universal methods of rockburst study used home and abroad and taking the actual situations of the project into account, we take the primary terrestrial stress and uniaxial compressive strength as the quantitative evaluation indexes for the prediction and evaluat ion of rock burst. The rockburst degree of the project is determined at last in the light of macro analysis and quantitative evaluation.
