Detection method of bearing capacity of big tonnage full sized foundation in simulated conditions

Abstract

The invention relates to a detection method for bearing capacity of a big tonnage full sized foundation in simulated conditions, comprising following steps: (1) investigating; (2) preparing; (3) determining the sequences of piles for settlement detection and for heaped load, which can be implemented by the following steps: placing a pile for heaped load (2) in the detection area; placing a plurality of piles for settlement detection (8) on the both side of the pile for heaped load (2), placing a plurality of bearing beams (9) on the piles for settlement detection (8) and the pile for heaped load (2), placing a plurality of displacement sensors (10) on one side of the bearing beams (9); placing a bearing steel plate on a plurality of hydraulic jacks (3); placing a bearing steel beam (4) on the bearing steel plate, placing a plurality of protective piles (11) under the bearing steel beam (4); (4) performing protection operation during settlement detection; (5) loading; (6) unloading; (7) compiling a detection report according to detection results. The invention reduces the steps of foundation processing, realizes construction of ocean engineering structures in non-sliding areas; moreover, implementation of this method is not limited by geological conditions, the detection can be carried out at any place.

Description

technical field [0001] The invention relates to a detection method of foundation bearing capacity, in particular to a large-tonnage full-scale foundation bearing capacity detection method that provides a basis for bearing capacity for the construction of non-slide areas of large structures such as offshore oil platforms. It belongs to the field of offshore oil engineering. [0002] Background technique [0003] In offshore oil development projects, various platforms such as oil production platforms, living platforms, and central processing platforms need to be built offshore. Platforms generally include: offshore engineering blocks, underwater support structures - jackets, single points and other offshore engineering structures. These marine engineering structures are generally prefabricated on land first, and then transported to sea for assembly. With the rapid development of marine engineering, the volume and weight of marine engineering structures are also increasing. E...

Problems solved by technology

[0007]2. If the existing bearing capacity detection method needs to obtain a deeper level of site bearing capacity, it needs to excavate the site, which increases the need for foundation treatment of the non-slide area of ​​the module link

[0008]3. Existing bearing capacity testing methods are greatly affected by geological conditions
