摘要
由于CRD(Cross Diaphragm)工法施工工序较多,支护结构复杂,为了提供可靠的初支设计参数,必须根据隧道要求、地质参数计算初支应力、应变。该文针对某CRD工法施工的隧道工程,运用有限元法进行受力分析,为隧道初支混凝土配筋设计提供依据。
As CRD method has many construction processes and supporting structure is complex,stress and strain of primary support structure need to be calculated to provide reliable design parameters based on tunnel requirements and geological parameters.In this paper FEA method is used to analyze stress status of a tunnel constructed with CRD method,the calculation results could be taken as basis for concrete reinforcement design of tunnel primary support.
