摘要
中国经济发达城市主要集中在东部沿海地区分布,大部分城市地层条件为河流冲积地貌,或为沿海海蚀地貌。在该类地层中施工不可避免的遇到富水非均质砂卵石地层,且城市环境复杂、人口密集。在此类地层中进行轨道交通区间施工多选择盾构法施工。因此,对于分析砂卵石地层中的盾构施工对于地表变形影响显得很有必要,因为对于该地层施工时地表变形监测的分析至关重要。
Chinese economically developed cities are mainly concentrated in the eastern coastal areas,most of the city＇s stratigraphic conditions are river alluvial landscapes or coastal sea-eroded landforms. Construction of this type of formation inevitably encountered water-rich heterogeneous sand and gravel stratum,and the urban environment is complex and densely populated. In such strata of rail transit interval construction more choice of shield construction. Therefore,it is necessary to analyze the influence of shield construction in sand-gravel stratum on the deformation of the ground surface because the analysis of surface deformation monitoring during the formation construction is very important.
