摘 要 本篇毕业设计通过中化岩土工程有限公司研发中心办公楼岩土工程勘察报告整理，详细介绍了岩土工程勘察的步骤、方法和原理，并对可采用的地基处理方式进行论证及CFG桩的施工工艺进行阐述。 其中，工程勘察的内容主要包括以下几个方面。 (1) 场地工程概况：概括介绍了场区所在地区的交通位置、经济地理、自然气象、区域地质构造、地震、工程地质分区与评价； (2) 场地工程地质条件：明确了建筑物的地下水条件、地形地貌、地层结构和不良地质现象等情况并介绍了勘察的目的、要求、方法； (3) 工程地质综合评价：主要介绍了土工试验、物理力学指标并对地基土的承载力和各岩土层的性质的评价； (4) 场地地基综合评价：对场地稳定性、建筑适宜性及基坑开挖进行评价。 根据工程勘察对地基处理有以下几个方面： (1) 地基处理方案：针对目前比较常用的水泥粉煤灰桩（CFG桩）进行该建筑物基础方案设计； (2) 针对水泥粉煤灰桩（CFG桩）从施工、造价和工期等几方面进行了论证 (3) 水泥粉煤灰桩（CFG桩）施工工艺：具体阐述了CFG桩的施工顺序、设备选配和施工工艺等方面的工艺及注意事项。 关键词：岩土工程勘察 基础论证 CFG桩 Abstract This graduate paper deals in great detail with the steps, methods and principles of the geotechnocal survey according to doing the engineering investigation report of ZHONG HUA engineering company , official building era, and the foundation can be used to conduct feasibility studies and handling of CFG pile construction technology described . Among them, the engineering survey covers the following aspects： (1) site engineering situation: an overview of the field area where the transportation position, economic geography, natural calamities, regional geological structures, seismic, geological zoning and evaluation;  (2) site engineering geological conditions: clear the building of the underground water conditions, topography, stratigraphy and geological phenomena such bad situation and describes the purpose of inspection, requirements and methods;  (3) comprehensive evaluation of engineering geology: major introduced soil test, physical and mechanical indexes and the bearing capacity of foundation soil and the soil layer of the nature of the evaluation;  (4) comprehensive evaluation of the foundation site: on site stability, construction and excavation suitability evaluation. According to survey on the ground treatment projects in the following areas:  (1) Ground Treatment: Aimed at the more commonly used cement and fly ash pile (CFG pile) and the underwater foundation bored piles for the building design;  (2) for more than two piles (ce
