摘要
Abstract
To master the development and distribution of internal forces in the shaft structure to guide earth excavation and lining construction, dynamometers are installed on the reinforcement at different elevations in different directions in the shaft structure to measure the force so as to monitor changes of the internal forces in the shaft structure during the construction period. The monitoring results show that the shaft structure is mainly in a compressed state during the construction period. The circumferential pressure of the shaft structure is greater than the vertical one at the same elevation. The structural stress in the center of diaphragm wall structure is greater than that in the substructure, and the circumferential pressure in the substrucure of the lining wall is greater than that in the center. The earth excavation and lining construction is performed according to the section of six meters in length. The structurale force is the maximum when constructed to the fifth and sixth floor. The calculated results show that the safety factor of structure is within the allowable range. The monitoring results provide guidance for the earth excavation and lining construction, and they also provide a reference for the monitoring, design and construction of other similar shafts.关键词
