摘　　要：岩土工程勘察报告应以土力学理论为基石,以技术标准及规范为路标,依据客观、真实的基础资料,研析合理的岩土工程参数,提出恰当的评价及建议。基于岩土工程勘察中的问题,对以下三方面展开讨论:采用标贯法进行液化判别评价应注意计算公式中地面标高选择原地面还是后期整平地面问题,必要时应分不同标高进行评价;浅埋基岩以上地基处理方案如建议嵌岩刚性桩与土共同作用,应明确计算模型为土岩组合地基;应考虑场地的地形条件、区域地质条件及结构设计条件,综合分析确定抗浮设防水位。The geotechnical investigation should be based on the theory of soil mechanics,the technical standards and codes are the road sign,based on the true data,study and analysis about reasonable geotechnical engineering parameters,and put forward the best evaluation and suggestions.The paper mainly elaborates the discussion of three aspects:the liquefaction judgment evaluation using the SPT method should pay attention to the calculation formula of the ground elevation and select the original ground or the later ground elevation,if necessary,it should be calculated separately according to different elevations.If the foundation treatment scheme above the shallow bedrock is recommended of work together with the pile and the soil,the calculation model should be clearly calculated as the soil-rock composite ground.The terrain conditions,regional geological conditions and structural design conditions of the site should be considered,and the fortification water table against uplift should be comprehensively analyzed to determined.
