摘要
试掘进施工是泥水盾构施工的一项关键技术,该文以南京长江隧道Φ14.93 m 泥水盾构施工为背景,对试掘进的工作内容和主要目的进行介绍,并结合距离始发井 75 m 的一处池塘的原位试验,对盾构施工引起的地表沉降变化规律和泥水压力的取值进行了研究。
Trial driving construction is a key technology for slurry shield tunneling.Taking slurry shield construction of Nanjing Yangtze river tunnel as background and combining experiments located on a pond where is 75 m from the shaft well,this article introduces the content and purpose of trial driving,and analyzes the variation rule of surface settlement and the technical requirements of slurry pressure set due to shielding construction.
