摘　　要：论文以广西某海港穿越航道深海管道工程为例,概述了工程的地形地貌特征、周边复杂环境、抗震需求、钻孔布置要求及主要勘察工作。评估了水土腐蚀性和岩土层渗透性,并分析了不良地质作用、隧道段工程地质条件及危险性较大的分部分项工程。针对发现的地质难题,提出了盾构设计、基坑支护、既有建筑保护、红树林生态保护及现场检验监测的系列建议。论文可为同类工程的勘探、设计与建设提供宝贵参考。Taking the example of a deep-sea pipeline project crossing navigation channels at a seaport in Guangxi,this paper outlines the topographic and geomorphic characteristics,surrounding complex environment,seismic requirements,borehole layout specifications,and primary investigation works of the project.It evaluates the corrosivity of soil and water as well as the permeability of geotechnical layers,and analyzes adverse geological effects,engineering geological conditions in the tunnel section,and high-risk sub-projects and divisional works.In response to the geological challenges identified,a series of recommendations are proposed regarding shield tunneling design,foundation pit support,protection of existing buildings,mangrove ecological conservation,and on-site inspection and monitoring.This paper provides valuable reference for exploration,design,and construction of similar engineering projects.
