基于昆明市某农贸市场拟建场地的工程地质条件研究

Research on engineering geological conditions based on the proposed site of a farmer′s market in Kunming

工程地质条件研究是提高工程建设质量和确保工程施工顺利的基础,本文研究表明:拟建区域地下水对砼结构的腐蚀性等级为微腐蚀,对砼结构中的钢筋的腐蚀等级为微腐蚀;场地属稳定的建筑场地,适宜拟建工程建设,但存在特殊性岩土,主要有人工填土、软弱土层、残积土及风化岩,对桩基成桩及成桩质量有一定的不利影响;拟建场地地基土为不液化地基,在Ⅷ度地震烈度下,可不考虑地震液化的不利影响。

The study of engineering geological conditions is the foundation to improve the quality of engineering construction and ensure the successful construction of engineering.This paper showed that the corrosion level of groundwater in the proposed area to concrete structure was micro corrosion,and the corrosion level of steel reinforcement in concrete structure is micro corrosion.The site was a stable construction site which is suitable for the proposed engineering construction.However,there are special soils,mainly including artificial fills,soft soil,residual soil and weathered rock,which had adverse impacts on the pile foundation and pile quality.The foundation soil of the proposed site is a non-liquefied foundation,and the adverse effects of seismic liquefaction do not need to be considered under the seismic intensity of 8 degrees.
