Foundation design of Haikou International Duty Free City project(plot 5)
The project is located in Haikou New Port,close to Qiongzhou Strait,within 1000m from the port pool of Haikou New Port.The site is rich in groundwater and has obvious geological characteristics of volcanic rock area of the island.Making full use of the medium-weathered basalt with an average thickness of 8m and inclined distribution on the base surface,the rock-socking anti-anchor rod is set to effectively solve the overall anti-floating problem under the condition of uneven mass distribution on the upper part.Meanwhile,according to the basic test data of anti-anchor rod,the layout of anti-anchor rod is optimized through overall collaborative analysis.In the calculation and analysis of foundation software,the coefficient of subgrade reaction is set in different regions,and the unfavorable influence of uneven foundation is fully considered to design the whole raft foundation.This article mainly introduces the foundation design characteristics of this project,and clarifies the design standards,parameter selection,calculation methods and key technical measures,aiming to provide useful reference and reference for the foundation design of such projects.
