编制起重吊装施工方案时,首先要进行设备起吊过程的静力分析。根据这一分析结果选择钢丝绳、卷扬机、滑车组等机具、布置锚点,对设备和机具进行强度和稳定度核算,以及对吊装过程预见性的说明和指导。静力分析的结果是一批几何数据和受力数据,这些数据要求数量上的完整和质量上的准确。静力分析所依据的数学模型应尽量符合设备吊装过程的实际,这是先决条件。一般说来,越是接近实际情况,考虑因素越多,数学模型就越复杂。这样,就增加了静力分析的困难。有时,要求在短时间内,进行大量的运算。以便及时的提供出若干种方案,通过分析对比,得出最佳方案。起重吊装的最佳方案有两个要求,首先是 Preparation of lifting construction program, we must first carry out the lifting process of static analysis. According to the results of this analysis, select the wire ropes, winches, trolleys and other equipment, layout anchors, equipment and machinery for the strength and stability of the accounting, as well as the hoisting process predictive instructions and guidance. The result of static analysis is a set of geometric data and force data, which are quantitatively complete and of good quality. The mathematical model on which static analysis is based should be as realistic as possible for the hoisting process of the equipment, which is a prerequisite. In general, the closer it is to the actual situation, the more considerations, the more complicated the mathematical model. This adds to the difficulty of static analysis. Sometimes it requires a lot of computation in a short period of time. In order to timely provide a number of programs, through analysis and comparison, come to the best solution. The best solution for lifting and lifting has two requirements, first and foremost
