摘要
以采用管棚注浆的洞室为研究对象,通过采用三维有限单元法分析了高压注浆过程中围岩的应力场、位移场及渗流场分布规律,揭示了高压注浆对围岩挤密效果及对地下水的挤出作用,从而有效指导高压注浆在隧道软弱地段的应用。
Taking cavity grouting pipe cave as studying object, through adopting three-dimensional finite element method, it analyzes the stress field, displacement field and the flow field distribution of high pressure grouting process, reveals its effect on the rock crowd density and on groundwater of extrusion, so as to effectively guide the high-pressure grouting in the tunnel in soft section.
