Combined with successful application of cast-in-place concrete GBF thin wall box structure system in residential building works of Shanxi coal central hospital,from formwork,reinforcement work,box installation and allocation,concrete work,construction supervision and other aspects study is made.

1概述GBF薄壁箱体现浇空心混凝土结构体系借鉴了预应力空心板为减轻自重，将板的腹部适当挖空的形式，不同之处在于它是全现浇的，整体性比预应力空心楼盖改善很多，且空心率大很多。与普通楼盖体系相比，该楼盖的自重明显减轻，对结构的抗震有利。

The major content of this thesis are as follows:1 Performed FEM analysis before strengthening, and to find out the reason for the cracking and present a strengthening scheme;2 Performed nonlinear FEM analysis before and after strengthening, and to get the varying rule of the relative displacement between the on-site cast concrete side wall and that between the precast concrete arch and the floor, as well as the stress distribution of the gallery;3 Performed on-site observation experiments on the 7~th gallery, and to get the varying rule of the relative displacement between the on-site cast concrete side wall, as well as that between the precast concrete arch and the floor.4 The results of the computation were compared with those of experiments, which verified the effect of the strengthening.

本文的主要工作有： 1 对加固之前的廊道结构进行有限元计算，找出廊道底板开裂的原因，提出加固方案； 2 对加固前后廊道结构进行非线性有限元计算，得到加固前后廊道两现浇边墙相对位移、拱顶与底板相对位移随水库水位变化的规律和廊道结构的应力分布情况； 3 进行廊道加固前后现场观测试验，得到廊道两现浇边墙相对位移以及拱顶与底板相对位移随水库水位变化的规律； 4 对比分析加固前后现场观测试验与非线性有限元计算所得结果，论证加固方案的合理性，验证加固效果。

In cast-in-place concrete structure, high-strength cement concrete hollow tube technology is the common beam, floor slab of ribs, prestressed plate without bond after an in-situ development of the new structure of the new system.

The design structure characteristics of the telephone connects the line box are two times parting planes with pin gate style, and side core-drawing structure.

ABS树脂注射压力对于薄壁、长流程、小浇口的制品或耐热、阻燃等品级，要求较高些；对于厚壁、大浇口的制品则可低些。

With rapid development of express way and city traffic and the type for city bridges, interchanges and viaducts such as continuous curved girder bridges are widely used. To get beautiful linetype, the top structure of bridge is required to apply cast-in-place technology. Therefore scaffold construction technology for beams are greatly applied.

随着桥梁结构型式的发展，以及近年来高速公路及城市交通的迅猛发展，变宽桥、弯桥等复杂的预应力混凝土结构得到了广泛的应用，因线型限制，桥梁上部结构一般采用现浇，这样有支架现浇技术得到了广泛的应用，同时应用中的技术、安全问题也日益突现出来。
