摘要
本文以澜沧耿马地震时昆明震害调查资料为基础,结合地震史料,研究了昆明市区震害的不均匀分布,烈度有两度的差别。相对高烈度区与历史强震破坏的重震害点大部分重合。据此分析了震害重复特点及其与地质构造和沉积盖层的关系。本文可用于研究昆明市区及邻区强震对市区可能造成震害的大致分布,为震害预测、防震抗震和城市规划提供一些依据。
In this paper, based on the hazard investigation data in Kunming when the 1988 Lancang-Gcngma earthquake occurred and combined with the historic data, the inhomogeneous distribution of earthquake hazard in Kunming metropolitan area is studied, and the intensity difference varied in two degrees. The relative high-intensity areas are overlapped on the most destructive points of historical, large events, with which repetition character of earthquake hazard and its relation to the geological structure and sedimentary overburden are analysed. The present data can be applied to study the approximate distribution of possible earthquake hazard in Kunming metropolitan area and its vicinities, providing bases for the hazard prediction, earthquake prevention and relief, and city planning.
