海口市海甸岛建筑场地类别划分探析

摘要

海口市海甸岛作为海口市文化、教育、医疗、居住、休闲娱乐的新兴商业中心区域,近年进行了大量的工程建设,因该区域存在有巨厚的软弱可震陷和可液化土层,地基基础方案普遍采用复合地基浅基础或桩基础,前者加固深度或后者桩端均应达到非液化和非震陷的硬土层中一定深度.文中试图从该区域大量岩土工程勘察钻孔中找出硬土层的分布规律,进而去了解场地类别划分特点,对本区域岩土工程勘察在场地类别划分方面具有指导意义,同时对该区域地基基础初步设计中场地类别确定具有借鉴意义.%Haidian island has a large number of engineering construction projects in recent years as Haikou city culture,education,health care,residential,leisure entertainment emerging business center area.Because of the there are soft soil earthquake sinking and liquescent soil,shallow foundation and pile foundation are widely used.The former pile reinforcement depth or the latter end shall reach the liquefaction and hard soil layer with the settlement of certain depth.This paper tries to find out the hard soil layer distribution law from a large number of geotechnical engineering drilling for understanding the characteristics of the divisional method of classifying building site.This paper has a guiding significance in site classification for construction.The preliminary classification of the site is of reference significance
