APPLICATION OF SYNTHETIC GEOPHYSICAL PROSPECTING METHODS TO EVALUATION OF COLLAPSE IN YULIN, FUSHUN

摘要: 利用测地工作、重力测量、高精度磁测、甚低频电磁法、电测深测量、浅层地震折射波法等物探方法,勘查评价了抚顺榆林局部塌陷区.利用物探方法可查明本区内的断裂构造、地下空洞、含水层位的分布情况,并综合所有物探成果及地质、地形测量工作成果进行推断解释.研究了该塌陷区沉降与塌陷的机理,总结塌陷原因,指出塌陷隐患部位.Abstract: Some geophysical prospecting methods, such as gravimetry, high-precision magnetic measurement, VLF electromagnetometry, electrical sounding and shallow seismic refraction, were used to evaluate the collapse area of Yulin, Fushun. These methods can determine the distribution of faults, underground caves and aquifers. The prospecting result, combined with geologic and geodesic information, may be used to infer and interpret collapses. After a study on the mechanism of collapse and subsidence, the reason for the collapse is concluded, and the potential areas of collapse are pointed out.
