【摘要】 复杂的边坡工程地质条件决定了建设摩崖石刻工程的位置和规模,但边坡上发育的崩塌、坠石等地质灾害和多变的地形地貌条件严重影响了边坡地质工程勘察的安全性、准确性和勘察技术方法的有效性,本文应用孔间电磁波层析成像技术探测和评价边坡工程内破碎带、岩溶以及岩体完整性变化等地质工程问题以及地质解释的关键技术.电磁波衰减特征及电磁波衰减吸收系数的变化趋势和异常结构特征可以有效地反映边坡岩体内节理发育带、岩溶以及场区具控制作用的溶蚀断裂带的发育深度及影响范围,评价边坡岩体完整性的垂向分带和空间分区特征,为边坡工程建造提供科学依据.更多还原

【Abstract】 The location and size of cliffside carvings is controlled by the complicated engineering geological structures of high slope.Safety and veracity of geotechnical investigation and validity of surveying techniques are limited owing to geological hazards and complicate landform in studying area.In this paper,some key techniques are studied in applying Electromagnetic Wave Tomography to investigating the distribution and depth of fissures and closely-spaced fissure zones,karst cave,and karst faults.Furthermore,the integrity of slope rockmass is evaluated according to the diversification characteristics of rock electromagnetic absorption coefficient.As a result,Electromagnetic Wave Tomography is valid to investigate the complicated geological structure of slope engineering.更多还原
