Methods: retrospective analysis was used. The subjects were 50 pregnant women in our hospital. All the subjects were informed and signed the consent form. According to different nursing intervention methods, the subjects were divided into observation group and control group to compare, analyze and record the actual nursing intervention effect data and information. Results: after practical research, analysis and observation, it can be found that the basin function of pregnant women in the observation group is good, and the effect of postpartum basin rehabilitation is obvious, which is significantly better than that of pregnant women in the control group. The data comparison has statistical significance (P < 0.05). Conclusion: rehabilitation treatment after natural delivery can improve the clinical effect, promote the early recovery of pelvic floor function and improve the quality of life of pregnant women.展开更多

Based on this important effect,and to discuss the relationship between cutting parameters and pressurerelief effect,this paper carried out a numerical simulation of grooving along bottom slab and two sides of gateway with finite difference software FLAC^（2D）.The results show that the control effect on floor heave in soft rock tunnel can be improved by selecting appropriate cutting parameters.Appropriately increasing the crevice depth in the middle of the floor can improve the stress state of bottom slab by stress transfer. So the floor heave can be more effectively controlled.To lengthen the crevice in the corners of roadway can simultaneously transfer the maximum stresses of bottom slab and two sides to deep rock,and promote the pressure-relief effect.Extending the crevice length and crevice width on both sides within a certain range can decrease the stress concentration in the corners of roadway,and reduce the deformation of two sides.The cutting position beneficial to restrain the floor heave is close to the bottom slab.展开更多
