某堤基广泛分布淤泥、淤泥质土等软土层，导致汛期或海潮来临时险情频发，严重影响堤防的安全运行。基于工程勘察、土的原位和室内试验等工作，划分了堤基地质结构类型，分析了软土的空间分布特征和物理力学性质。研究表明该软土具有含水率高、孔隙比大、高压缩性、高灵敏性、透水性微弱、强度低等特点，堤基主要存在软基沉降变形、抗滑稳定和岸坡稳定等工程地质问题。

At one levee,the soft soils such as mud and muddy soil are distributed widely,which affect the levee safety heavily during flood season or sea tide.According to both the field and laboratory tests,the geological structure of the levee is defined,and the distribution and physical-mechanical properties are studied.The results show that these soft soils have special properties,such as higher water content,greater void ratio,higher compressibility,higher sensitivity, lower permeability and lower capacity.Therefore,the engineering geological problems,such as settlement deformation, stability against sliding and slope stability,are inevitable.
