The invention discloses a support replacement structure and a support replacement method for a foundation pit. The support replacement structure comprises a fender post, a plurality of circuit purlins, a plurality of inner supports and a plurality of support replacement beams, wherein the circuit purlins comprise a top circuit purlin, a bottom circuit purlin and a plurality of middle circuit purlins; the inner supports comprise a top inner support, a bottom inner support and a plurality of middle inner supports which are separately arranged on the inner sides of the corresponding circuit purlins; and the support replacement beams correspond to the middle circuit purlins one by one, the support replacement beams are located on the inner sides of the corresponding middle circuit purlins, oneends of the support replacement beams are connected to the corresponding middle circuit purlins, the other ends of the support replacement beams cling to an exterior wall of a main body structure ofan underground building and face an internal parting wall of the main body structure, a vertical frame of the main body structure and an exterior wall of another main body structure vertically intersected to the exterior wall of the main body structure clinging to the support replacement beams. A soil pressure outside the foundation pit is transferred to the exterior wall, the internal parting wall or the vertical frame by means of the support replacement beams, the lateral soil pressure is resisted by means of side resistance of the exterior wall, the internal parting wall or the structure ofthe vertical frame body.
本发明公开了一种基坑换撑结构和方法，包括：围护桩；若干围檩，围檩包括顶部围檩、底部围檩和若干中间围檩；若干内支撑，内支撑包括顶部内支撑、底部内支撑和若干中间内支撑，分别设置在对应的围檩的内侧；若干换撑梁，若干换撑梁与中间围檩一一对应，换撑梁位于对应的中间围檩的内侧，并且换撑梁的一端连接于对应的中间围檩，换撑梁的另一端紧贴于地下构筑物的主体结构外墙上，且正对主体结构内隔墙、主体结构竖向框架、及与换撑梁紧贴的主体结构外墙垂直相交的另一主体结构外墙处；本发明通过换撑梁将基坑外的土压力传递到外墙、内隔墙或竖向框架上，利用外墙、内隔墙或竖向框架本身的结构抗侧能力抵抗侧向土压力。
