唐山市地质灾害环境分析和城市规划

Geological Disaster Environment Analysis and City Planning of Tangshan City

地震与岩溶塌陷是影响唐山市城市建设与发展的两大地质灾害。以弹性力学理论为研究基础,运用有限单元法,对唐山市的构造应力场进行了计算与分析。根据计算结果,进行潜在强震危险区预测分析。同时结合岩溶塌陷等地质资料,通过与唐山市城市规划的对比分析,对城市规划和防灾减灾问题做了初步探讨,提出了几点结论和建议。

Earthquake and karst collapse are two geological disasters that affect construction and development of city. Based on elastic mechanics and finite element method, tectonic stress field of Tangshan city is calculated and analyzed. Strong shock danger zones are predicted based on the calculating results. At the same time, combined with karst collapse data, city planning and disaster prevention and mitigation are discussed elementarily through the analogous analysis between city arrangement of Tangshan and the geology data, some conclusions and suggestions were given.
