The invention discloses a method and structure for steel pipe and bracket combined support of a foundation pit slope. The method comprises the following steps: firstly, a bracket is downwards drilled in a slope toe design position of the foundation pit slope; then, one ends of steel pipes are inserted in drilled holes of foundation pit slope soil, and the other ends of the steel pipes are fixed on the bracket; and the steel pipes are fixed by grouting between the steel pipes and the drilled holes of the foundation pit slope soil. The invention further discloses the structure for steel pipe and bracket combined support of the foundation pit slope. A traditional method of soil nailing support for foundation pit is changed from an anchor mode to a support mode for supporting; and the steel pipes are used for supporting the weight of soil. Compared with the length of a soil nail in traditional soil nailing support, the length of the steel pipes only needs to penetrate through a slip surface by a certain distance, so that the length is greatly reduced; and the support structure and the support method are simple in principle and structure, excellent in stability, capable of recycling the bracket structure, low in manufacturing cost, fast in construction period and low in technical requirements on foundation pit support constructors.
