摘要
Abstract
Taking an underground tunnel passing beneath an existing urban road as an example,the influence of underground tunnel excavation on the deformation of the upper road subgrade is analyzed.It is found that the maximum settlement of the ur-ban road is located in the middle of the underground section;the settlement rate of the road is accelerated when the under-ground tunnel is excavated directly below the road,and the settlement value during the period accounts for 41％of the to-tal settlement.Based on the analysis of the influence of the full-process construction,the concrete influence law of the under-ground tunnel construction on the deformation of the urban road above is clarified,and the research results can provide refer-ence for similar projects.关键词
