Abstract

The invention discloses a drilling in-situ testing device for testing the mechanical parameters of an engineering rock mass and a use method of the drilling in-situ testing device. The device comprises a penetration sounding loading system, a multi-point testing rotational positioning system, a propelling support system, a hydraulic loading system and a control system. The penetration sounding loading system and the multi-point testing rotational positioning system are connected together through a bearing and can move along with a propelling lever of the propelling support system, and finally,the whole device is regulated and controlled through the hydraulic loading system and the control system. The device and the method drill and load and test the engineering rock mass in situ, the deformation and fracture characteristics of the rock mass having different lithological characters and different drilling depths and the load-displacement curve and data of a surrounding rock in the loading process are acquired, the relevant technical indexes and parameters are obtained through conversion, the device and the method are favorable for accurately simulating the numerical value and effectively designing the supporting scheme in the construction process, the supporting strength and the engineering strength are guaranteed, and the guarantee is provided for the safety construction of theengineering like rock and soil, water resources and hydropower, and mines.

Description

technical field [0001] The invention relates to a device and method for testing mechanical parameters of engineering rock mass, in particular to an in-situ multi-point testing device and method for mechanical parameters of engineering rock mass. Background technique [0002] The physical and mechanical parameters of rock mass are the basic data for the implementation of geotechnical, water conservancy, hydropower and mining projects. For these projects involving roadway support, it is necessary to clearly measure the mechanical parameters of the surrounding rock of the roadway to ensure the strength and stiffness of the support design scheme At the same time, to predict the deformation and failure characteristics of the surrounding rock in the excavation state through numerical simulation, the mechanical parameters of each layer of the surrounding rock must be accurately measured to obtain reliable results and guide the project. [0003] There are two traditional methods for...
