Research On Huang Family Slope First Tunneling Project Time Optimization

This article embarks from the project time management, and unifies the characteristic of railroad engineering construction, conducts the research on Huang family slope first tunnel section (DK1603+080 ~ DK1603+184) engineering project time management and optimization. It expatiates upon project engineering plan, engineering progress, time management and the optimization, carries on the analysis in the project progress plan, and conducts the time optimization research for the project plan by means of essential chain.This article carries on the introduction to survey of the Huang Family Slope first tunneling; the project key and difficulty, thus further illustrate the formation of project timing progression by using network technology, and introduces the application for project activity the duration time estimate to estimate this project activity time, utilizes of essential chain to optimize this project progress, and achieved the goal which project time management is optimized to the Huang Family Slope first tunneling project. This paper proposes the corresponding guarantee measure, ensure this project press plan successful complete.
