摘　　要：施工导流风险度计算目前常用的方法包括JC法和Monte-Carlo法,当功能函数非线性化程度过高时,JC法计算精度无法满足工程需要,Monte-Carlo法的准确计算则依赖于庞大的样本容量与模拟次数,因而不易实现。因此,基于Monte-Carlo法施工导流风险度计算模型,引入Matlab强大的随机数发生器指令和数值计算功能编制程序,生成数量充足且具有代表性的样本容量,实现施工洪水过程及泄流建筑物泄流过程仿真模拟的程序化,使Monte-Carlo法计算施工导流风险度变的准确快捷。实例应用结果表明,程序计算速度快,可操作性强、准确度高,在工程实践中取得了良好的应用效果。The calculation methods of construction diversion risk include the JC and Monte-Carlo methods.The JC method does not satisfy the engineering requirements when the function appears nonlinearity.The accuracy of MonteCarlo method depends on a large amount of samples and number of simulation times.Therefore,it is not easy to be computerized and programmed.Based on the construction diversion risk calculation model and Monte-Carlo method,the Matlab compiler was introduced to simulate the construction flood and the discharge process of the discharge structure and the risk calculation of the construction diversion.The application results show that the program has fast calculation speed,good operability and reliability,and has achieved good application effect.
