| 摘 要： | 根据杭州地质条件,结合盾构施工工艺,系统地分析了杭州地铁盾构区间施工过程中主要的地质风险源,得出了对杭州地铁建设影响较小的风险源的种类有区域断裂构造、特殊岩层、地下障碍物（抛石）;较大的风险源主要有特殊土层、不利复合地质、有害气体和地下障碍物（已有桩基）,并提出了防范措施。

| Abstract: | According to geological conditions in Hangzhou,combined with the shield construction technology,systemically analyzes the major geological risk source proceeding from construction process of metro shield section in Hangzhou,it comes to a conclusion that risk-sources which have small influences on metro construction in Hangzhou include regional fracture structure,Special Strata,underground obstruction（riprap）;while what have large influences mainly include special soil,unfavorable complex geological structure,harmful gases and underground obstruction（existing pile）.Then the author proposes some protective measures. |
