摘要
文章通过对立井井壁破裂现象及破裂原因的深入分析 ,找出了与破裂现象相吻合的井壁破裂因素 (温度 ) ,对长期以来理论界认为的“表土沉降是井壁破裂的决定因素”的观点进行了较有说服力的反驳 ,这是更好的寻求防止井壁破裂的措施及预测井壁破裂的时间提供了理论基础 。
The shaft wall fracture factor(temperature)relevant to the fracture phenomenon is located through the in depth analysis on the shaft wall fracture and cause of fracture.The paper retorts persuasively the dominant theory that surface soil sedimentation is the determinant factor of shaft wall fracture.It provides theoretical basis for both search for measures to prevent the wall fracture and prediction of time of wall fracture as well as the design of shaft wall.
