摘要
在富水砂层中选择土压平衡盾构机掘进施工，对渣土改良有更高要求和难度。北京地铁6号线东部新城站。东小营站间地质构造为典型的富水砂层，结合该工程采用土压平衡盾构施工的成功案例，对富水砂层渣土改良技术加以总结，为以后类似工程提供经验。
Greater difficulties and requirement is unavoidable for the use of earth pressure balance shield machine in water-rich sand bed. The geological structure of the tunnel for Beijing subway line 6 [ Xincheng Station - Dongxiaoying Station] is the typical water-rich sand bed. Based on the successful case of earth balance shield tunneling construction, this paper concludes the improvement techniques for residue soil from water-rich bed and offers valuable experience for the similar construction afterward.
