摘　　要：通过研究安溪县某建筑场地工程地质条件,分析场地岩土工程特性、地震效应特征、稳定性与适宜性,对地基岩土体进行了综合评价。研究表明:拟建区域地下水对混凝土结构的腐蚀性等级为微腐蚀,对钢筋混凝土结构中钢筋的腐蚀性等级为微腐蚀,对钢结构的腐蚀性等级为弱腐蚀;拟建场地土的类型为软弱土—岩石,场地类别属Ⅰ—Ⅱ类,属对建筑抗震不利地段;拟建场地地基土不具备震动液化条件,抗震性能较好。建议本工程设计采用浅基础或桩基础,以中风化凝灰岩或强风化凝灰岩为基础持力层。By studying the engineering geological conditions of a building site in Anxi country,the geotechnical engineering characteristics,seismic effect characteristics,stability and suitability of the site are analyzed,and then the comprehensive evaluation of the foundation rock and soil mass was carried out.The research showed that the corrosion level of groundwater in the proposed area to concrete structure was micro corrosion,the corrosion level of steel bars in reinforced concrete structures was micro corrosion,and the corrosion level of steel structures was weak corrosion.The soil type of the proposed site was soft soil-rock,and the site category was I—II,which is unfavorable to the seismic resistance of the building.The foundation soil of the proposed site did not have the condition of seismic liquefaction,and the seismic performance was good.It is suggested that shallow foundation or pile foundation be used in the design of the project,with moderately weathered tuff or strongly weathered tuff as the foundation bearing layer.
