摘　　要：为开展关于工程选址的可利用性评价,建立区域构造稳定性评价模型。从地质结构、断裂活动、地震条件和应力特征4个方面,建立指标体系,利用B-P神经网络模型,对甘谷地进行构造稳定性评价。评价值表明目标地构造较稳定,符合实际情况。The purpose is to establish a regional tectonic stability evaluation model for the selection of the engineering site.The indexes for the model are determined according to geo-structural features,fault activity,seismic conditions and stress features,and,then,the evaluation of Gangudi tectonic stability was carried out using B-P neural network.The result revealed a comparable stability,which is in line with the realities.

关 键 词：工程选址 区域构造 稳定性评价 B-P模型
