摘要:

超高层建筑施工过程中面临着巨大的安全风险，构成“人-机-环”系统，施工风险预警难题需考虑人员、装备、环境因素耦合的影响，本研究按一般状态与极限状态分别考虑系统的失效可能性，采用整体钢平台装备的承力构件为决定性关键环节，提出超高层建筑施工风险预警指标体系与方法。首先，通过考虑风险因素耦合的事故演变路径分析和失效模式分析，结合施工现场监测条件，提出风险预警指标体系的核心指标；然后，提出包括人员指标、环境指标、装备指标和熔断指标在内的施工风险预警指标体系，以及各指标的分级确定准则，采用指标折减的方法体现多因素耦合对预警指标的影响，建立适用超高层建筑施工风险预警方法；最后，选择超高层实际工程开展案例分析。结果表明：将人员、环境风险因素耦合影响考虑为对装备指标的折减，可以作为项目风险状态判定的有效依据，建立适用于超高层建筑施工的风险预警方法。该方法充分考虑风险因素的耦合影响，通过有限元模型计算获得指标预警值与折减系数参考表，具备一定的科学性和可行性。

Abstract:

This paper focused on the early construction risk warning issue in the construction of super high-rise building,the potential failure of the system was studied according to the general state and radical state.Taking the load-bearing components of integral steel platform equipment as the key risk link,a construction risk early warning index system and method for super high-rise building were proposed.Firstly,based on the analysis of accident evolution path and failure mode considering the coupling effect of risk factors,the core indexes were proposed,combined with the monitoring conditions.Then,the early-warning index system including human,environment,equipment and fuse indexes,as well as the classification and determination criteria,are proposed.The way of reducing index was adopt to reflect the impact of multi-factor coupling effects,and applicable early-warning method was established.Finally,a project was chosen to carry out case analysis.The results showed that the method of considering the coupling effects of human and environment risk factors as a reduction of the equipment indexes could be used as effective basis for judging the risk status of the project,to establish a risk early-warning method suitable for the construction of super high-rise buildings.This method fully considered the coupling effects of risk factors,and obtained values of early-warning indexes and reduction coefficient table through finite element model calculations.It was feasible.
