摘要
以澳门新城填海区30多个岩土勘察项目、957个软土样品的室内土工试验数据为基础,采用数理统计方法分析该区域全新世海积软土的工程地质特性,给出了物理力学性质指标统计值以及参数相关性,并与洋山港、连云港、温州、福建宁德等地区的软土进行差异性分析。研究结果表明,澳门新城填海区软土具有含水率高、孔隙比大、粒度很细、黏粒含量较高、透水性极弱、扰动后土体强度衰减快等特性。研究成果对于澳门填海造陆工程具有实际意义,也可为其它区域软土工程特性分析与工程建设提供参考经验。
Based on the indoor geotechnical test data of more than 30 geotechnical investigation projects and 957 soft soil samples projects in Macao New City reclamation area,using mathematical statistical methods to analyze the engineering geological characteristics of Holocene marine soft soil in this area.The statistical values of physical and mechanical property indexes and the correlation of parameters were given.The differences between the soft soil of Yangshan Port,Lianyungang,Wenzhou and Ningde of Fujian Province were analyzed.The research results show that the soft soil in Macao New City reclamation area has some characteristics,such as high water content,large porosity ratio,very fine particle size,high clay content,very low water permeability,and rapid attenuation of soil strength after disturbance.The research results have practical significance for Macao reclamation project,and also provide valuable reference experience for the analysis of soft soil engineering characteristics and engineering construction in other regions.
