膜结构的积水是膜结构工程中一种常发生的事故。通过对膜结构积水的基本原理进行分析,考虑了膜结构受力后的变形和膜材料的蠕变性质,对找形后膜结构的合理形态进行判断,给出了防止膜结构积水的合理控制条件,并用推导的公式对实际发生的膜结构积水工程事故进行了分析。建议的膜结构积水控制条件是对正常设计、施工的膜结构而言的。由于膜材的松弛特性和其他荷载联合作用,给出的控制条件是防止膜结构积水的最小值。
Water accumulation in membrane structure is a common accident in membrane structure engineering. By analyzing the basic principle of water accumulation in membrane structure, considering the deformation of membrane structure and the creep property of membrane material, the reasonable morphology of membrane structure after finding shape is taken into account. Reasonable control of the conditions, and the use of the formula derived from the membrane structure of the actual waterlogging engineering accidents were analyzed. Recommended membrane structure Hydrostatic control conditions are for the normally designed, constructed membrane structure. Due to the slack nature of the membrane and the combined effects of other loads, the control conditions given are the minimum values to prevent water accumulation in the membrane structure.
