取排水工程预制箱涵出运下水的稳定计算

Stability Calculation of Prefabricated Box Culvert′s Launching for Water Intake and Drainage Project

采用气囊搬运大型钢筋混凝土构件是目前国内较常用的一种安全、经济的施工工艺,但直接采用气囊搬运箱涵下水并不多。结合工程实例,介绍直接利用气囊搬运箱涵下水时的稳定计算,并用计算结果指导施工。

It is a safe and economical construction technology most commonly used at present in China to transport large R.C. members with gas cushion, but box culverts are seldom launched into water with gas cushion. This paper presents the stability calculation for box culvert＇s launching into water with gas cushion combining an engineering project, the result of which can be used to guide construction.
