为了适应唐山市重建规划的需要,并探索和解决我国强震区普遍存在的地震工程地质问题,勘察技术研究所进行了“唐山强震区地震工程地质”的专题研究。经过三年多现场调查、勘探、测试和室内整理分析工作,现已提交了研究报告。研究报告分为五个部分: (一)地震断裂——从本区地震地质背景入手,研究了断裂展布及活动特点,探讨了发震断裂的震源机制及鉴别方法,根据地震前后地形变、余震震中迁移及古地震构造
In order to meet the needs of reconstruction planning in Tangshan City and to explore and solve the seismic engineering geological problems that prevail in the strong earthquake areas in China, the Institute of Survey and Technology carried out a special study on “Earthquake Engineering Geology of Strong Seismic Areas in Tangshan”. After more than three years of field investigation, exploration, testing and interior finishing analysis, a research report has been submitted. The research report is divided into five parts: (1) Earthquake rupture - Starting from the seismic geological background in this area, the fracture distribution and activity characteristics are studied, and the focal mechanism and identification method of seismogenic faults are discussed. According to the terrain changes before and after the earthquake, Migration of aftershocks and palaeo-earthquake structure
