Abstract_Chinese:\r现有考虑机械故障的施工进度仿真研究均采用机械的整个故障时长来反映故障影响,忽略了故障机械未能在原单元活动结束前完成维修,且剩余故障处理活动不影响施工进度的情况,因此难以保证施工机械故障分析的准确性.本研究对引水隧洞施工机械因故障退出工作、维修后重新投入使用的全过程进行精细模拟追踪,提出基于机械故障精细分析的引水隧洞施工进度仿真方法.首先,在仿真过程中追踪各施工机械的运行轨迹,并确定机械故障时刻;其次,通过分析故障处理时间与剩余单元活动的关系,确定机械故障类型;再者,推导不同机械故障类型下单元活动延误时间的计算公式,以精细分析机械故障的影响后果;最后,通过施工仿真方法获得机械故障影响下的隧洞开挖进度,并通过敏感性分析获得不同施工机械故障对进度影响的敏感指数.研究结果表明,相较于现有考虑机械故障的施工进度仿真方法,该方法可在精细分析施工机械故障的基础上,获得更符合工程实际的仿真进度.\r

Abstract_English:\rThe existing construction schedule simulation,which considered machine failure,utilized the whole troubleshooting time to reflect the impact of the machine failure. These studies ignore the situation of failure to complete maintenance work before the end of the original unit operation,and the remaining fault handling activities do not affect schedule;this consequently affects the accuracy of machine breakdown analysis. In this study,fine simulation and tracking of the whole process of machine withdrawal from work due to failure and reinstallment after repair are performed,and an approach for simulating the construction schedule of diversion tunnel based on fine analysis of machine breakdowns is proposed. First,the working trajectory of each machine was tracked during simulation,and the failure moment could be determined. The machine failure type could be determined by analyzing the relationship between troubleshooting duration and the remaining original operation. In addition,formulas for calculating the operation delay caused by two types of machine breakdown were derived to realize the fine analysis of failure consequences. Finally,construction schedule considering machine breakdowns was obtained with the construction simulation method,and the sensitivity index of diverse machine failures on construction schedule was obtained through sensitivity analysis. Compared with current construction schedule simulation methods,the proposed approach can realize fine analysis of machine failure and obtain a simulation schedule that is more in line with actual schedule.\r
