| 摘 要： | 昆明机场残积红土既是区域内重要的土地资源,更是各类工程建设的建筑地基,由于机场及临近区域内小江地震活动断裂带和普渡河断裂带地震活动频繁,使研究区处于较不稳定状态。本文采用MIDAS GTS有限元数值分析软件,利用动三轴试验所得出的结果,分别对昆明长水国际机场玄武岩残积红土、砂页岩残积红土地层下典型的地下结构进行了抗震模拟研究。所获得的研究成果,对红土分布区城市及村镇房屋建筑地基和地下空间结构抗震安全稳定性评价具有一定的指导意义和实用价值。

| Abstract: | The residual red soil in Kunming Airport is not only an important land resource in the region,but also a building foundation for various types of construction.Due to the frequent seismic activity of the Xiaojiang earthquake activity fault zone and the Puduhe fault zone in the airport and adjacent areas,the study area is in a relatively unstable state..In this paper,the MIDAS GTS finite element numerical analysis software is used to simulate the typical underground structure of the basalt residual red soil and sand shale residual red soil layer in Kunming Changshui International Airport.The research results obtained have certain guiding significance and practical value for evaluating the seismic safety and stability of urban and rural housing construction foundations and underground space structures in red soil distribution areas. |
