The invention provides a constructing method for a basic pit at the upper part of a shield tunnel; the H-type steel inserted in a stake reinforces the soil body round the shield tunnel and encloses the basic pit; the stake provided in the pit is pumped and deformed; the separating stake divides the basic pit into plurality of small basic pits with width less than 8m; each basic pit is processing the digging by the barn jumping method; 2-4m soil is remained to the last layer of soil body for each basic pit; each small basic pit is divided into plurality of small blocks for digging the small blocks; after digging the small soil body, each small bottom plate is casted and each soil body is poured to compete the construction in 7 hours; the methods above can reduce the pumping and deformation while digging the basic pits to conform to the request of the shield tunnel and satisfy the requirement of the normal operation.

The invention discloses a tunnel convergence monitoring method, which utilizes a measuring device to measure a tunnel section, inputs actually measured data to a computer so as to implement ellipse fitting processing, computes a fitted ellipse equation, determines the position of the section center, implements the elimination processing of parasitic error and random error of the measured data, computes the deformation degree of each measured point relative to the section center, and finally outputs a figure that is unfolded by taking the polar angle of the section center as horizontal axis to show the deformation degree of the tunnel section. The tunnel convergence monitoring method implements reasonable processing of the measured data of the tunnel section, can reflect the actual deformation situation of the tunnel section more veritably, and can be widely applied in the monitoring working of circular tunnel convergence.
