混凝土喷射法与模筑法在地铁车站基坑防水方面的优劣分析

摘要:

近年来,随着我国经济发展,城市轨道交通工程发展迅速,全国大中型城市均在不断的开发建设。城区内,其一般为地下工程。地下工程的防水质量直接关系到它的使用安全和寿命。作为地下工程的地铁车站,国内常用的基坑防水方案有混凝土的挂网喷射法及模筑法,本文结合相关科研成果及方案应用实例,进行两种方案的优劣分析,旨在明确两种方案的适用条件,并能为类似工程提供比选参考。

Abstract:

In recent years, with China"s economic development, urban rail transit engineering has developed rapidly, almost the main cities are under continuous development and construction. In urban areas, it is generally an underground engineering. The waterproof quality of underground engineering is directly related to its safety and service life. Subway station as the underground engineering,usually,the gunite concrete and model-building concrete was applied to the waterproof for subway-station’s excavations.This paper combines relevant scientific research achievements and application examples, analyze the advantages and disadvantages of the two schemes, clarify the applicable conditions of the two schemes, provide comparison and selection reference for similar projects.
