港池疏浚深度-10.00范围内第①1层—素填土:松散，分布局限，港池开

港池疏浚深度-10.00范围内第①1层—素填土:松散，分布局限，港池开挖需全部清除；第①淤泥质粉质黏土：流塑～软塑，高压缩性为主，广泛分布；第②层粉质黏土层：硬可塑—硬塑状态，中偏低压缩性，物理力学性质较好，分布广泛，疏浚面积约39000m2。工区基岩为强风化及中风化花岗岩，坚硬，仅分布在港池东南侧,疏浚面积约2830m2。

① layer 1 - plain fill within the dredging depth of harbor basin -10.00: loose and limited distribution, and all harbor basin excavation needs to be removed; ① mucky silty clay: fluid plastic ~ soft plastic, mainly high-pressure shrinkage, widely distributed; Layer ② silty clay layer: hard plastic hard plastic state, medium to low compressibility, good physical and mechanical properties, widely distributed, with a dredging area of about 39000m2. The bedrock in the work area is strongly and moderately weathered granite, hard, only distributed in the southeast of the harbor basin, with a dredging area of about 2830m2.

Layer ①1 within the range of dredging depth of the harbor basin -10.00-plain fill: loose and limited in distribution, and the harbor basin excavation needs to be completely cleared; ① Silty silty clay: flowing plastic ~ soft plastic, with high compressibility, widely distributed; ② Silty clay layer: hard plastic-hard plastic state, medium to low compressibility, good physical and mechanical properties, wide distribution, dredging area of about 39000m2. The bedrock in the work area is strongly weathered and moderately weathered granite, which is hard and only distributed in the southeast of the harbor basin, with a dredging area of about 2830m2.
