建筑工程逆作法(国外英文资料) After excavation, it is found that the eccentricity is larger. Economic performance USES uni-axial, general basement wall and foundation pit enclosure wall in the form of the joining together of two walls, on the one hand out the separate enclosure wall, on the other hand can within the scope of construction land and maximise the basement area and increase effective use area. In addition, the support system of the enclosure wall is replaced by the basement floor structure, which saves a lot of support cost. And floor structure of the support system, can also solve the special plane shape building, or local floor loss brought about by the support of difficulty, and is more reasonable. Because of these reasons, and the total construction period shortened, thus in soft soil area for high-rise building with multistory basement, using uni-axial has obvious economic benefits. You can save 25% to 35% of the total cost of underground structures. Environmental benefits Aspects: (1) the noise due to uni-axial during construction of the basement is to use first floor surface integral casting, and down excavation, so the noise due to the surface of floor of block in the construction is greatly reduced, so as to avoid the delay time limit for a project for night construction noise problem. (2) dust: the usual ground treatment is open and open, creating a lot of construction dust, which affects the image of the city. Using reverse course construction, due to its construction operation under closed surface, the dust can be reduced to maximum extent. Social benefits (1) transport: due to uni-axial take surface support, at the bottom of the construction method, so the scope for in city traffic construction, it will continue to be opened to traffic on the ground, hoof, road underground operations, avoiding the loss due to traffic jam around. (2) using the reverse course, the + 0.00 plate structure is finished first and can be supported by the structure itself. Becaus
