深圳市某工程人防地下室设计若干问题探讨（Discussion on Design of civil air defense basement of a project in Shenzhen） Discussion on Design of civil air defense basement of a project in Shenzhen Brief introduction: This article through to the top 306 industrial plant of Shenzhen City Tairan Industrial Co. Ltd. the basement (including air defense) analysis of engineering design, the design of the basement of a high-rise building with the civil air defense two problems put forward some suggestions. Key words: civil air defense basement design 1. project introduction 306 senior industrial plant of Shenzhen City Tairan Industrial Co. Ltd is the 1 18 storey buildings (1 floors underground) the frame shear wall structure of the high-rise building industry. The building area is 31200m2, the building height is 79.8m, the seismic intensity is 7 degrees, the frame grade is 3, and the shear wall grade is 2. Basement area 3908m2, including air defense area 1390m2, divided into two civil air defense units, storey 4.4m, pile foundation using prestressed concrete pipe pile. Considering the problem of civil air defense basement design in a peacetime problem, which should not only consider the small load of regular use, meet the needs of large space building use problem, but also consider the defense when the load is larger, the structure is difficult to meet the large space problem, how to coordinate the two kinds of state requirements the following few in the civil air defense design has some experience for reference. 2., civil air defense structure design features Civil air defense, that is, civil air defense, the task of peoples air defense, is based on the needs of national defense, mobilizing and organizing the masses to take protective measures to prevent and mitigate the harm of air strikes. In addition to evacuation measures, it is also one of the most important measures against air defense in wartime. The main contents of the basement structure design includes two aspects: one is the main struc
