优化网络技术在公路施工组织中的应用

THE APPLICATION OF BETTERMENT NETWORK TECHNOLOGY IN HIGHWAY CONSTRUCTION ORGANIZATION

本文从施工组织的角度出发，将一个工程进行项目分解，并根据《公路工程预算定额》、各工作的实际工作面大小、施工单位的现有设备情况和设备租赁情况，计算确定各工作的持续时间和所需的人工数、各种机械数。运用网络技术，按施工逻辑关系，将各项目各工作联成一个连带整体，形成多级网络图，然后编制程序，以工程施工全过程的人工、机械均衡为目标，以满足工期需求为前提，进行计算并优化。优化计算后得出任一区段时间全部工程所需的工人数和机械数，任一时刻各工作完成的百分率，为施工计划及工程投标提供依据。施工进程中，根据实际完成的情况，执行软件，可迅速修改未来计划。

From the viewpoint of construction organization,this article decomposes the items of an engineering.According to 'Highway Engineering Budget Quota',the actual size of working surface,the present equipment,the construction unit and the equipment rent situation,it calculates and determines the continued time and required worker numbers,various number of mechanism of each work.Using network technology,and in accordance with the construction logic relations,it puts each item and each work into a related entirety,and forms multistage network drawing.It performs calculations and betterment through programming,making the number of workers and mechanic balance as objective and under the prerequite of meeting the requirement of construction duration.After calculations and betterments it gets the required number of workers and mechanisms of whole engineering at any duration of time,the percentage of completion of work at any time.It supplies the basic for construction planning and engineering tender.During the construction,according to the actual completion of work,it performs software and amends the future plan quickly.
