Summary:The utility model relates to a composite supporting structure for a deep foundation pit close to a high slope under the condition of a soft stratum, and the composite supporting structure is adopted aiming at the special working condition that the high slope is close to the excavation area of the deep foundation pit. The composite supporting structure comprises a near-high-slope supporting system and a deep foundation pit supporting system, wherein the near-high-slope supporting system comprises an existing gravity retaining wall and a miniature recoverable pre-stressed anchor rod; the deep foundation pit supporting system comprises fender posts, top beams and pre-stressed anchor cables. The high slope supporting structure has the advantages that the high slope is temporarily supported by the recyclable anchor rods in consideration of possible disturbance to the adjacent high slope in the excavation process of the deep foundation pit, so that the stability of the high slope in the excavation process of the fo
