摘要
本文以工程地质研究为主线,在区域稳定性评价的前提下,以地质条件的基本要素———地貌单元、地层时代和地层岩相组合为基础,建立地层岩相及其波速特征概化的地质模型,并进行工程地质区段划分,进而做地震反应分析并得出地面运动特征和地震反应谱,同时以地貌———地层岩相组合判断砂土液化及其它地震效应的分布。这套工作程序和方法就是地震小区划的“工程地质———地震工程准则”。文中还以“焦作———鹤壁矿区地震工程地质研究及小区划”为例,具体说明了这一准则的可行性。
Based on the evaluation of regional stability,the author sets up geological model of stratigraphic facies and wave velocity,taking topographic unit,stratigraphic age,and stratigraphic facies as major factors.The classification of engineering geological segments has been carried out.Furthermore,earthquake reaction has been discussed and the surface movement and earthquake reaction spectrum have been analyzed.Meanwhile the author infers the soil liquation and earthquake effect through topographic-stratigraphic facies association,which is the so-called 'engineering geological-earthquake engineering criteria'.A case study of Henan Province is performed to test the feasibility of this criteria.
