【摘要】 拟订围堰施工计划即设计河道截流后各月围堰修筑应达到的高程，在运用随机过程理论研究了堰前水位的概率特性后，提出了围堰施工动态保证率，从而导出了导流围堰施工计划的动态概率设计方法．更多还原

【Abstract】 The main feature of constructional planning of cofferdam refers to finalize the monthly level of cofferdam during construction. Probability characteristic of water level before cofferdam is first studied by using the theory of stochastic process, and the dynamic assurance coefficent of the cofferdam construction is then calculated. On the basis of that, a probability based design method of cofferdam constructional planning is presented.更多还原
