To large number of proposed buildings,large-scale engineering,and complex geological conditions in large-scale land reclamation projects,there are many geological risks that may lead to quality hazards during subsequent construction.Taking the east operation area of Yantian Port as an example,the project characteristics,engineering geological features,and experience of Shenzhen area are studied and technically analyzed.Based on the comprehensive assessment of traditional geological hazards and the geological risk sources existing in this project,a geological risk analysis process for ports formed on large land area is proposed.According to this process,risk analysis is carried out and the risk levels are divided.The results show that:there are four high-risk factors in the project,including the easy breakage zone of the hydraulic fill silt insertion plate,the difficulty in determining the bedrock roof in soft rock areas,the difficulty in determining pile foundation parameters,and the easy collapse of holes in the construction of gravel filled soil pile foundations.Risk prevention measures and treatment plans are proposed,and feedback analysis is conducted on the actual problems and risks analysis during the construction process,which is verified and beneficial for avoiding risks during construction,providing guidance for the design and construction of similar large-scale water transportation projects.
