铁路工程沟槽基坑开挖定额结构体系研究

本文针对目前铁路工程预算定额中部分专业涉及的基坑、沟槽及管道开挖定额子目,结合现场实测数据,对现有沟槽基坑开挖定额结构体系进行研究和梳理。从适用性角度,重点对挖土和挖石定额子目的人工、机械效率做了对比分析,提出了统一定额单位、梳理地质类别、优化结构体系等建议,为铁路工程造价标准的制修订提供参考。

Study on Trench and Foundation Pit Excavating Quota Structural System in Railway Engineering

This paper focuses on the excavating quota involved in the trench,foundation pit and pipeline in current Railway Budget Quota. Combining with on-site data,the current trench and foundation pit excavating quota structural system are researched and presented. In terms of applicability,this paper emphasises on the comparative analysis of the manual and mechanical efficiency of navvy and quarry quota,proposes to unify the rating unit,combs the geological category and optimizes the structural system to provide reference for the railway engineering cost standard revision.
