【Abstract】 With reference to the mechanism of shaft wall fracturing under the conditions of ground setting, the paper points out that the employment of pressure relieving troughs is an effective way for the rehabilitation and reinforcement of the fractured shaft wall. The paper also presents analysis and study on the key technologies to be employed in the design for grouting in shaft wall fractures, cutting the pressure relieving troughs and shaft wall lateral reinforcement. The results indicate that the designs for future shaft wall rehabilitation and reinforcement will be more reliable.更多还原
