为提高道路施工过程中工期分析的准确度,结合风险分析理论,建立了一个新的道路工程工期风险计算方法。该法首先根据道路工程施工特点,给出了阶段允许工期、阶段工期期望、阶段工期风险率、阶段工期权重、阶段工期风险的定义;然后结合简单施工流程图,对道路工程工期风险计算方法进行讨论;最后,以佛山“一环”路堤施工过程中的工期风险计算为例,演示了该计算方法的使用过程,验证其实用性。
In order to improve the accuracy of construction schedule analysis during road construction, a new risk calculation method of road construction duration is established based on risk analysis theory. Firstly, according to the characteristics of road construction, this paper gives the definition of allowable construction period, expectation of construction period, risk of construction period, weight of construction period and risk of construction period. Combined with simple construction flow chart, Finally, taking the construction period risk calculation of Foshan “One Ring ” embankment as an example, the process of using this calculation method is demonstrated and its practicability is verified.
