The invention relates to a multi-layer basement supporting structure and a supporting construction method. The supporting structure comprises a wall body and a multi-layer supporting structure; the wall body comprises prefabricated enclosure walls and cast-in-place concrete columns; each layer of supporting structure comprises a circular arched beam, a diagonal brace, an inclined strut and a steel latticed column; the prefabricated enclosure walls can play a role in retaining soil, passive earth pressure is borne, and stress is more reasonable; the prefabricated enclosure walls are directly used as basement outer walls, so that the construction cost is saved; meanwhile, the prefabricated enclosure walls are formed in a prefabrication factory, concrete does not need to be poured on site, and the construction period of a basement is greatly shortened; the prefabricated enclosure walls can serve as anti-seepage walls to prevent external underground water from flowing into the basement when the basement is excavated, and active earth pressure is increased; the joint part of a transverse concrete slab and a vertical concrete slab is a weak stress part and a weak water seepage part; and the cast-in-place concrete columns are adopted at the joints of the transverse prefabricated enclosure walls and the longitudinal prefabricated enclosure walls so as to avoid leakage.
本发明涉及一种多层地下室支护结构及支护施工方法，支护结构包括墙体，墙体和多层支护结构；墙体包括预制围护墙和现浇混凝土柱；每一层支护结构均包括圆环形拱梁，对撑、斜撑及钢格构柱；本发明采用预制的围护墙能够起到挡土作用，承担了被动土压力，受力更加合理；预制围护墙直接作为地下室外墙，节约了工程造价；同时预制围护墙在预制厂中已经成型，不必在现场浇筑混凝土，大大缩短了地下室工期。预制围护墙可作为防渗墙，防止地下室开挖时外面地下水流入地下室，增加主动土压力。横向混凝土板和竖向混凝土板交接部位是受力薄弱部位，同时也是渗水的薄弱部位。在横向预制围护墙和纵向预制围护墙连接处采用现浇混凝土柱以避免渗漏。
