Abstract:Statistical analysis of the deformation monitoring data of 20 station pitsꎬfrom Zhengzhou urban rail transit line 1and first
phase line 2 are given in this paperꎬThe pit risk grade is divided by the depthꎬandthe monitoring projects of ground settlementꎬtop
horizontal displacement of pile (wall)andbody horizontal displacement of pile (wall)are studied.Themeasuredvaluesdistributionof
each monitoring project is definedꎬandthemathematical statisticsresultsof themeasured data aregiven.Themaximumvalueposition
of body horizontal displacement of pile (wall) is takenꎬand the influence of foundation pit depth is studied. The deformation law of
foundation pit engineering isespecially analyzedinthisarea.Theresearch achievement may giveimportant guidancetothedeformation
control of foundation pit engineering in Zhengzhouꎬand it can also be usedfor reference engineering in similar area.
