海堤软土堤基地质特性及其工程危害分析

为了查清海堤软土堤基对工程的危害性，为设计提供准确可靠的地质依据，通过对珠海市小林联围海堤现场地质调查资料及各种物理力学性试验数据的分析，得出软土的地质特性主要为不均匀性、较高灵敏度、流变性、低强度、高压缩性和低透水性。并结合工程设计布置方案，进一步分析得出软土对工程的危害有：引起构筑物沉降变形、引起构筑物滑动破坏和引起塌岸。针对软土的危害性，在施工时采取了切实可行的加固措施，并取得了良好效果。

Analysis on geological characteristics of soft foundation of sea embankment and its hazards

In order to explore the hazards of soft foundation of sea embankment and provide a solid geological basis for design,the main geological characteristics of soft foundation is acquired through the field geological data investigation on Xiaolinlianwei embankment in Zhuhai City.We analyze the measured data from mechanical and physical tests,and identify that the soft soil is characterized by inhomogeneity,higher sensitivity,rheology,low strength,high compressibility and low permeability.Combining with engineering design and layout scheme,its hazards are made clear by further analysis,namely,deformation and slide-failure of buildings,and bank collapse.The feasible reinforcement measures are adopted in the construction with satisfying effects.
