摘要

为解决利用现有模板台车一次性将洞门斜切段浇筑成型的问题，以拉法山隧道等环宽斜切式洞门施工为例，分别从经济性和实用性等方面对以往类似隧道洞门施工方法进行综合对比分析，采用在台车端头自制加长段模板的方法，并通过对模板放样、模板加工与安装等环节加以改进和控制，以达到快速施工和整体浇筑的目的。

Abstract

Comparison and contrast is made among different tunnel portal construction technologies in terms of economical efficiency and practicability, so as to select proper construction technologies for the bambootruncated portals of Lafashan tunnel. In the end, technologies, including preparing formworks for the extended section of the tunnel portal, settingout of the formworks, fabrication of the formworks and installation of the formworks, are adopted for the tunnel. In this way, integral portal is cast rapidly by means of the existing formwork jumbo. 

Key words： Lafashan tunnel; bamboo truncated portal; formwork jumbo
