摘　　要：深入分析了沉管法和盾构法各自的技术特点,结合港珠澳大桥隧道工程,对沉管隧道和盾构隧道进行了方案初设,并从施工难度、风险综合评估、地质适用性、工期造价、环境影响等方面进行对比分析。比较而言,沉管隧道更占优势一些,因为沉管隧道造价低、风险小、工期短。虽然采用沉管隧道与外界的相互影响较大,但是采取必要的措施,影响可控,因此最后建议采用沉管法修建港珠澳大桥海底隧道。The technology characteristics of immersed tunnel and shield tunnel were analyzed.Based on the characteristics of Hongkong-Zhuhai-Macao Bridge,scheme design was performed for both immersed tunnel and shield tunnel and comparisons were made in terms of construction difficulty,risk assessment,geological applicability,construction period,engineering cost and environmental impact.The comparison shows that immersed tunnel scheme takes more advantage because it involves lower cost,lower risks and shorter construction period.The shortcoming of immersed tunnel is higher levels of interaction with external environment.However,with proper control measures,this effect can be minimized.As a result of the study,the immersed method was recommended for Hongkong-Zhuhai-Macao Bridge.
