Abstract

The invention discloses a multi-base gravity type base structure which comprises a primary gravity base and more than three secondary gravity bases, wherein the secondary gravity bases are connected through a horizontal carriage to form a polygon; the primary gravity base is located in the polygon; the primary gravity base is connected with the secondary gravity bases through the horizontal carriage; and an inclined carriage is fixed on the secondary gravity bases. According to the invention, a single past gravity type base is divided into a plurality of gravity type bases, so that the contact area of the bases and the foundation is increased, the acting force from the bases to the foundation is decreased and the adaptive capacity and the stability of the gravity type bases to the foundation are improved.

Description

technical field [0001] The invention relates to the foundation of a towering structure, in particular to a multi-pedestal gravity foundation structure. Background technique [0002] For natural soft soil foundations, the bearing capacity of the foundation is often difficult to meet the requirements of structures, and special structural components are usually required to be built. [0003] The foundation structure types of marine engineering mainly include: single pile foundation, gravity foundation, suction foundation, multi-pile foundation and floating foundation. At present, the single gravity foundation structure commonly used in China is widely used in marine engineering such as ports and wharves because of its huge weight to maintain the stability of structures, simple structure and good stability. Such as figure 1 As shown, due to the huge weight of the single gravity foundation, the bearing capacity of the seabed is difficult to meet the requirements, and riprap tre...
