摘要
文章主要针对沿海区域某高层建筑岩土工程进行了勘察分析与评价,勘察过程中,结合现场调研、钻探取样、土工试验等多种手段,详细研究岩土层的分布、厚度.结果表明,该区域岩土体主要由人工填土、沉积岩、花岗岩和构造岩组成,局部存在孤石和砂土.岩土体整体稳定性较好,但局部存在软弱层,可能对高层建筑的基础设计和施工造成一定影响.综合考虑了岩土体的工程性质、地下水条件、环境因素等,对高层建筑岩土工程的设计和施工提出了建议,为工程顺利实施提供了科学依据.
Abstract
This paper mainly focuses on the investigation analysis and evaluation of the geotechnical engineering for a high-rise building in coastal area.In the process of investigation,combined with field investigation,drilling sampling,geotechnical test and other means,the distribution and thickness of rock and soil layers are studied in detail.The results show that the rock and soil mass in this area are mainly composed of artificial fill,sedimentary rock,granite and tectonite,with localized presence of boulders and sandy soil.The overall stability of rock and soil mass is good,but there are weak layers locally,which may have a certain impact on the foundation design and construction of high-rise buildings.Considering the engineering properties of rock and soil mass,groundwater conditions,environmental factors,etc.,suggestions for the design and construction of high-rise building geotechnical engineering are proposed,which provides a scientific basis for the smooth implementation of the engineering.
