钻孔弹模仪在三峡永久船闸中隔墩岩体力学特性研究中的应用

Application of boring elastic modulus instrument to studying rock mass mechanical characteristics of central pier of permanent shipiock of TGP

主要阐述了钻孔弹模仪的设备结构、参数指标、测试方法与测试原理及测试设备的标定。同时,并依此测试手段对三峡永久船闸中隔墩岩体卸荷范围的划定进行了测试。结果表明,该测试方法是可行的。

The equipment structure,parameter index,measuring method,measuring principle and equipment demarcation of boring elastic modulus instrument are described.Meanwhile,as a measuring method,the boring elastic modulus instrument has been used to define the scope of the unloading cranny on the rock mass of the central pier between the double chambers of the permanent shiplock of the Three Gorges Project.The measured results show that this measuring method is available.
