Abstract

The invention discloses a manufacture method of a large-scale geomechanical model. The method comprises the following steps of: (1) pressing prefabricated standard modules; (2) numbering the pressed prefabricated standard modules respectively and making a design drawing with standard modules being assembled into a model; (3) according to the design drawing, employing a caking agent in order to build the standard modules into a shape; (4) introducing a measuring line on a measuring element out of a model body and to connected with measurement equipment. According to a geomechanical model prefabricated standard module building forming method, the production process of a large-scale true three-dimensional mechanical model is improved, serious stratification of enclosing rocks and a deviation phenomenon of pre-buried measurement element caused by stratification molding in a present geomechanical model manufacture process are overcome, and the manufacture quality of the model is improved. The method has the advantages of high efficiency, being fast and economic, simple operation of equipment, uniform model entity, capability of scaled standardized production and the like, and the high quality operation of a three-dimensional mechanical model experiment is effectively ensured.

Description

technical field

[0001] The invention relates to a method for making a large-scale geomechanical model, in particular to a method of masonry molding using prefabricated standard modules. Background technique

[0002] With the rapid development of transportation infrastructure and the vigorous development of underground resources development, underground structures have been widely used in the fields of hydropower, transportation, resources, and energy. At the same time, the construction safety of underground cavern engineering has also received more and more attention and attention. With the increase of the buried depth of the underground engineering and the improvement of the engineering scale, the engineering geological conditions and hydrogeological conditions of the rock mass in the proposed underground engineering area are also becoming more and more complicated. The experiment is carried out to analyze and evaluate the stability of the surrounding rock of the undergroun...

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] like figure 1 , 2 shown,

[0036] A method for making a large-scale geomechanical model, the steps are:

[0037] 1) Prepare the material according to the experimentally determined mixing ratio and lay the weighed material in the pressing mold 1. The material weight of the prefabricated module 2 is (In the formula: Design volume for the model body). In order to ensure the convenience of construction, the number of the prefabricated standard modules is 2 The determination of the weight of the prefabricated module needs to be guaranteed Not more than 20Kg. The prefabricated module is in a square shape, and its length, width and height are all about 20cm. Considering that the size of the proposed model body is generally about 1m square, the total number of prefabricated modules 2 to be pressed is About 100-200 pieces.

[0038] 2) The m...
