摘要
拟研究的边坡工程为一废弃的采石矿山边坡,边坡高度约100m,边坡岩体内部岩溶断裂构造发育,岩体结构和完整性变化复杂。为利用现状边坡建造摩崖石刻工程,应采取有效的勘察技术手段详细、无损地查明边坡体内断裂构造、岩溶、岩体完整性等的分布特征并评价其对摩崖石刻工程建造的影响。本文详细分析了应用电磁波层析技术(EMT)探测边坡工程地质条件的有效性及其工程地质解释的关键技术。研究结果表明,电磁波层析成像技术可以有效地探测边坡岩体节理裂隙发育程度、断裂破碎带及溶洞的分布和发育特征,根据电磁波吸收衰减系数的变化有效评价边坡岩体完整性的分区分带的空间变化特征,为摩崖石刻工程建造和规划设计提供科学的技术依据。
This paper investigates a rock slope with height of 100m. It is an invalidated mine slope. The cliff side carving is going to be designed and constructed in this rock slope. But the complicated engineering geological struc tures will control the location and size of the cliff side carvings. Consequently, it is very important to investigate the development characteristics of faults, joints, kast caves, rock mass structures in this slope with valid methods. This paper studies the validity and some geological interpreting keys in applying the Electromagnetic Wave Tomography to investigating engineering geological conditions. As a result, the Electromagnetic Wave Tomography is able to in vestigate faults, karst caves and fissure zones, structure type of rock mass and zones in the slope. Furthermore, the change characteristics of rock electromagnetic absorption coefficient are valid to illustrate integrity zoning of slope rock mass. The result can provide the scientific evidence to the construction and design of complex geological slope.
