摘要
本项目位于海口市新海港,紧邻琼州海峡,距海口新海港港池1000m以内,场地地下水丰富且明显具有海岛火山岩地区地质特点。充分利用基础底面平均厚度8m、倾斜分布的中风化玄武岩,设置嵌岩抗拔锚杆有效解决上部质量分布不均匀条件下的整体抗浮问题,同时根据抗拔锚杆基本试验数据,通过整体协同分析优化抗拔锚杆布置。基础软件计算分析中采用分区域设置基底地基基床刚度系数的方法,充分考虑不均匀地基的不利影响,进行整体筏板基础设计。主要介绍了本项目的基础设计特点,明确了设计标准、参数选取、计算方法及关键技术措施等,旨在为同类项目的基础设计提供借鉴和参考。
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.
