摘　　要：针对深圳滨海区域的人工填土勘察难度大、成分和分布复杂、难以查明工程地质特性的问题,采用收集资料、地质钻探、原位测试、水文地质观测和室内试验多种方法获得人工填土勘察的相关数据,根据矩形网格算法原理,生成填土空间分布和地下水位等值线图。经数理统计和综合分析,得到填土测试的物理力学指标,推荐填土的相关岩土参数,进行特殊性岩土评价,并提出相应的工程建议。结果表明,通过科学的勘察方法和分析,可以合理解决填土勘察难点,预测和应对人工填土的复杂性,确保工程建设的安全和质量。To address the difficulties associated with fill investigations,such as complex composition,uneven distribution,and the challenge of identifying engineering geological characteristics,a series of methods are used including data collection,geological drilling,in-situ testing,hydrogeological observation,and laboratory testing,to obtain relevant data for the artificial fill,contour maps of fill spatial distribution and groundwater levels are generated using the principles of the rectangular grid algorithm.Through statistical and comprehensive analysis,the physical and mechanical indexes for the fill are derived,and the relevant geotechnical parameters are recommended,followed by an evaluation of special geotechnical characteristics and corresponding engineering recommendations.The results show that through scientific survey methods and analysis,we can reasonably deal with the difficulties of filling exploration,predict and deal with the complexity of artificial fill,and ensure the safety and quality of engineering construction.
