摘要
地面沉降对城市轨道交通建设和运营的影响越来越明显,分析现行规范高程贯通误差公式在地面沉降条件下的应用缺陷,提出顾及地面沉降高程贯通误差的计算新公式,同时针对地面沉降的影响给出应对措施,并建议制定和完善相关技术标准。
Impact of surface subsidence on urban rail transit construction and operation has become increasingly obvious.This article analyzes the deficiencies of the formula for assessing elevation errors of piercing in the current Norm when applied to the condition of surface subsidence and presents a new formula.Countermeasures for surface subsidence are put forward toge-ther with proposals to formulate and perfect relevant technical standards.
