摘　　要：Sand-gravel soil may not be suitable for structure use or excavation use as a result of their permeability and low-intensity.It may cause serious damage to the upper part of the structure for its considerable stress.How to assess and control the deformation of the ground is the main purpose of the soil reinforcement technology.Grouting is a method commonly used to meet those requirements.This study is designed to investigate the effects on shield construction in the sand-gravel stratum.Sand-gravel soil may not be suitable for structure use or excavation use as a result of their permeability and low-intensity. It may cause serious damage to the upper part of the structure for its considerable stress. How to assess and control the deformation of the ground is the main purpose of the soil reinforcement technology. Grouting is a method commonly used to meet those requirements. This study is designed to investigate the effects on shield construction in the sand-gravel stratum.
