地震作用下骆驼城土遗址的安全性评价
|
摘要
以甘肃高台地区国家级重点文物保护单位骆驼城土遗址为研究对象,对其依次采用实地勘察、室内土工试验、统计分析、数值模拟四种手段进行了研究。将可靠度理论引入有限元动力分析中,利用APDL语言编制程序,使用蒙特卡洛法进行一千次的抽样数值模拟后进行抗震概率性分析。从而实现了土遗址抗震安全性评价的一种新方法和手段。计算结果对于骆驼城土遗址抗震防护及加固具有重要的参考价值,同时也为类似土遗址的防灾减灾工作提供一定依据。
The Camel town,a typical soil relics which is the national key protection project of cultural relics in Gaotai county of Gansu province,is taken as the research object.The field investigation,geotechnical tests,statistical analysis and numerical simulation are adapted in the study.Through introducing the reliability theory into finite element dynamic analysis,using APDL language in programme,after one thousand times sampling numerical simulation by Monte Carlo method and the seismic probability analysis,a new method of seismic safety evaluation for soil relics is realized.The results has certain reference value for the seismic protection and reinforcement of the Camel town,and also provides a basis for preventing and mitigating disasters to same kind of soil relics.
