基于实地调研的纳西族民居抗震性能分析

Seismic Performance Analysis of Naxi Dwelling Based on Field Research

云南省丽江市是一个地震频发地区,近几十年来频繁遭受地震影响,损失惨重。对丽江市大研古城和白沙镇等地进行实地调研,通过走访当地居民和有关单位了解情况,根据纳西族传统民居围护墙体材料的差异将其木构架房屋分为土木结构、砖木结构和石木结构等;深入调查丽江历史上最为严重的1996年2月3日7.0级地震发生以来的真实情况,研究各类原生房屋受地震影响的状况及其发展和演变过程。在此基础之上提出民居抗震加固保护的措施和意见。

This paper made some detailed field research in Dayan Town and Baisha Town through visiting the local and the relative departments. The wooden framework dwellings are divided into soil-wood structure, brickwood structure and stone-wood structure depending on their enclosure wall materials. The paper studies the real situation since the most serious earthquake in Lijiang＇s history with M_L7.0 on Feb 3 ^（rd）, 1996 in depth, and investigates the seismic performance as well as the evolution process of different dwelling types. Finally, the paper puts forward some measures and opinions on dwelling seismic reinforcement and protection.
