Background
The principle of the reverse construction method is that a high-rise building underground structure is constructed layer by layer from top to bottom, namely, continuous walls or close-packed piles are constructed along the periphery of a basement of a building to serve as an enclosure structure of the basement outer wall or a foundation pit, meanwhile, piles are supported in the middle of construction floors at relevant positions in the building, so that a reverse vertical bearing system is formed, a layer of earthwork is dug from top to bottom, a layer of basement beam-slab structure is poured together with an earth mould, and after certain strength is achieved, the reverse vertical bearing system can serve as an inner horizontal support of the enclosure structure to meet the safety requirement of continuous downward construction. Meanwhile, the completion of the top surface structure of the basement creates conditions for the construction of the upper structure, so that the construction of the ground structure can be carried out layer by layer upwards at the same time.
The top-down construction method has the great characteristic that the temporary support is replaced by the basement board structure. Therefore, the structure is contracted in advance, the contradiction of finished product protection is outstanding, especially in the construction stage of a reverse construction method, only the vertical steel upright posts are used for supporting the self weight and the construction load of the built part, only a single pile is used for participating in stress under the front post formed by the bottom plate, and the bearing capacity is limited. Because the earthwork is excavated, the pit bottom uplift drives the steel upright post to move upwards, the steel upright post vertically sinks or rises under the combined action of downward load and upward uplift, the difference settlement between the steel upright post and the surface of the basement can cause the additional internal force of the structure, the structure can crack seriously, and the structure is permanently damaged. Therefore, detailed theoretical calculation must be carried out according to the construction flow before construction, and measures must be taken to prevent excessive differential settlement during construction.
