Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0033] This embodiment takes the deepening design of the anti-floating anchor in the basement of a commercial complex in Xindu District, Chengdu as an example. The design uses three 25 rebars, and the soil layer in the anchorage section of the bolt is mainly clay, fully weathered sandy mudstone, strongly weathered sandy mudstone, and moderately weathered sandy mudstone. , the characteristic value of the bolt's pullout resistance is 200KN. According to the geotechnical engineering investigation report of the project, there are 93 exploration holes deployed in the commercial complex area, figure 2 The engineering geological profile of one of the datums of the ...

Abstract

The invention discloses a method for rapidly determining the design length of an anti-floating anchor rod, relates to the technical field of building foundation construction, and solves the problems of low design efficiency and poor precision during length determination of the existing anti-floating anchor rod. The method comprises the following steps: acquiring elevation data of a roof of a drilling stable rock-soil layer in an anti-floating anchor rod deployment area; establishing a stable rock-soil layer roof elevation contour line grating file; establishing an anti-floating anchor rod areawater-resistant plate bottom elevation grating file; performing spatial superposition analysis by utilizing the anti-floating anchor rod point location grating file, the stable rock-soil layer roof elevation grating file and the water-resistant plate bottom elevation grating file to obtain a stable rock-soil layer roof elevation and a water-resistant plate bottom elevation; taking the sum of thedifference value between the bottom elevation of the water-resistant plate and the top plate elevation of the stable rock-soil layer at each anti-floating anchor rod point position and the depth valueof entering the stable rock-soil layer according to the design requirement as the design length of the theoretical anchor rod at each point position. The calculation efficiency and precision are greatly improved, the design time and design workload are saved, and the design precision is improved.

Description

technical field [0001] The invention relates to the technical field of building foundation construction, in particular to a method for rapidly determining the design length of an anti-floating anchor rod. Background technique [0002] Anti-floating anchor is a kind of anti-floating measures for underground structures in construction projects. It refers to the structural components set up to resist the upward displacement of buildings on it. on the contrary. [0003] Anti-floating anchors have been widely used in anti-floating measures for underground buildings and structures. Most anti-floating anchor design units often only require anti-floating anchors to enter the predetermined depth of the stable rock and soil layer in the design instructions, and do not determine the depth of each anti-floating anchor. For the specific length of the floating anchor, the detailed design of the anti-floating anchor needs to be carried out according to the survey results before constructi...
