摘要
本文简要介绍西南地区自然地理、地层岩性、地质构造、新构造断裂运动与地震活动、水文地质等地质环境特征及地震、地质灾害分布规律、形成机理及防灾减灾对策;结合工程实际研究论述了西北地区常见的不良地质现象及工程地质问题;系统总结了西北铁路工程地质50年的发展、成就与经验。
This paper gives the brief introductions to the geological environment characteristics of natural ge- ography,stratigraphic lithology,geolocial sturcture,rhegmagenesis movement,seismic acitvity and hydrologic geology in northwest zone,to allocation law and formation mechanism of earthquke and geological disasters in the zone,and to the countermeasures for preventing and decreasing natural disasters,researches and describes the unfavourable geological phenomena and engineering geolocial problems in the zone in combination with engineering practice,and systematically sums up the development,achievements and experience of engineering geology of railways in the zone for 50 years.
