施工期临时航道建设规模仿真

Simulation of temporary channel scale during construction period

针对航道建设过程中施工船舶与港口进出船舶相互影响环境下的施工临时航道建设规模难以论证的问题,采用计算机仿真研究手段,基于Flexsim仿真平台,结合工程案例,构建施工临时航道仿真模型,模拟航道工程疏浚及吹填施工的全过程。通过仿真试验,分析施工临时航道建设规模对施工工期的影响。结果表明,对于长度较短、通航密度不高的施工临时航道,建设规模对工期的影响有限,而储泥坑及吹泥站的规模也是影响工期的重要因素。

Aiming at the difficulty of demonstrating the construction scale of construction temporary channel under the environment of the complex interaction between dredgers and merchant ships in the course of waterway construction,we apply the computer simulation research method,establish a temporary channel simulation model based on the Flexsim simulation platform combining with engineering cases,simulate the entire process of channel dredging and reclamation works,and analyze the influence of construction scale of the temporary channel on the schedule through model experiments.The results show that the construction scale has a limited influence on the schedule for the construction temporary channel with a short length and low density of ship flow,and the scale of mud storage area and reclamation station is also an important factor in the schedule.
