中廊式混凝土框架受地裂沉降影响分析
|
摘要
西安是地裂缝灾害严重的城市,地裂缝的活动给城市建筑带来严重破坏,同时也给城市整体规划带来不可忽视的影响,在城市化进程逐步加快的社会经济背景下,给城市的可持续发展带来非常不利的后果。
地裂缝活动产生的不均匀沉降对建筑结构安全产生巨大危害,历史资料表明,地裂缝影响区建筑受其影响会产生局部构件破坏、整体倾斜甚至倒塌,严重威胁到建筑的正常使用和人民生命财产安全。
为了减小和防止地裂缝活动对建筑造成的破坏,陕西省制订了《西安地裂缝场地勘察与工程设计规程》(DBJ61--6—2006),建议主要采取避让措施,但是其中的最小安全避让距离的合理性还有待验证,因此深入分析地裂缝场地建筑安全性能具有非常重要的实际意义。
本文依据已有地裂缝未来50a沉降曲线,利用SAP2000有限元分析软件建立不同高度的框架结构模型,通过距离改变对比分析结构内力重分布情况,同时考虑填充墙对结构性能的影响,探索规程规定的地裂缝影响区最小避让距离缩短的可能性。
The ground fracture has become one of the leading urban geologic hazards recent years in Xi'an. Due to the activity of ground fissure, there have been destroyed badly to the urban building, created the great influence to the urban integrated planning, and given rise to the urban sustainable development under the background of the accelerating urbanization.
The differential ground settlements do big harm to the safety of the building for the ground fractures, the historical resources suggest that the buildings in the affected zone of the ground fracture will make the local member destroyed, then the whole building inclined and even collapsed, It treats the normal service of building and the security of people'life and property.
To decrease and prevent the building destroy due to the ground fracture, Specification for site investigation and engineering design on Xi'an ground fractures> (DBJ61--6—2006, J 10821-2006) has been drew up by Shaanxi province. It propose to adopt engineering let by method, the reasonableness of the minimal secure distance still have to be validated, So, it is of significance to analyze the safety of the structure in the effected zone of the ground fracture.
According to the future 50a subsidence curve of the existing ground fracture, we have built lots of frame construction models of the differential height with the SAP2000finite element analysis software, and compared and analyzed the redistribution of internal forces of the frame via the change of the distance, meanwhile, we also have considered the influence of the fill wall to the structure and properties, and are exploring the feasibility of the decreased distance of the minimal effected zone of the ground fracture defined in the Specification.
