Thermo-mechanical coupling analysis of APSE using submodels and neural networks

The sp Pillar Stability Experiment (APSE) is an in situ experiment for investigating the spalling mechanism under mechanical and thermal loading conditions in a crystalline rock. In this study, the thermo-mechanical behaviors in the APSE were investigated with three models: (1) a Full model with rough meshes for calculating the influence of tunnel excavation; (2) a Submodel with fine meshes for predicting the thermo-mechanical behavior in the pillar during the borehole drilling, heating, and cooling phases; and (3) a Thin model for modeling the effect of slot cutting for de-stressing around the pillar. In order to import the stresses calculated from the Full model to the Submodel and to define the complex thermal boundary conditions, artificial neural networks (NNs) were utilized. From this study, it was possible to conclude that the stepwise approach with the application of NNs was useful for predicting the complex response of the pillar under severe thermo-mechanical loading conditions.     

4^th Intemational Conference on DAM ENGINEERING（CALL FOR PAPERS AND EARLY REGISTRATION）

Organised by: Hohai University, Nanjing, China; China Society for Hydraulic Engineering;China Society for Hydropower Engineering. Introduction: With the rapid economic and industrial growth of many regions in Asia,the development of water resources is a vital element of the infrastructure to satisfy the ever-increasing demand for power, irrigation and drinking water supply. This development includes both the construction of new facilities and the rehabilitation of existing older plants. Dams are usually the key element in such facilities and their economic construction and safety are of paramount importance.

碎石填筑场地强夯加固机制及施工工艺

 This paper carried out the in-situ tests and laboratory tests to study the reinforcement mechanism and construction technology of a high fill airport under dynamic consolidation. The dynamic response of broken stone fills,of which gradation can not meet the specifications for earthwork construction,has been studied by measuring the acceleration. Then the relationship between compact energy,compact momentum(the height of hammer raised),the size of hammer and settlement,effective reinforced range were researched by numerical simulation. The results show that the acceleration of the range of sideways and downward of the broken stone fills is weaker than around. The plastic dissipation energy and volume of plastic zone of fills for every ramming are stable;while the settlement for each ramming is decreased because the plastic zone is increasing. The larger compact energy is,the larger settlement is;but the compact energy can not affect the ramming time for stable settlement. The settlement and plastic zone can be affected by the height of hammer raised and the size of hammer when the compact energy is constant. Construction technology indices were proposed by the research results.

Design and development of large-scale in-situ PRACLAY heater test and horizontal high-level radioactive waste disposal gallery seal test in Belgian HADES

In Belgium,the Boom clay was selected as a potential host formation for the disposal of high-level radioactive waste（HLW）.To demonstrate the suitability of Boom clay for bearing thermal load induced by the HLW,a large-scale in-situ heater test,called PRACLAY heater test,will be conducted in the underground research laboratory（URL） in Mol.Owing to the limitations of the test（a short period of time compared with that considered in a real repository,different boundary conditions,etc.）,the test is designed to simulate,in a conservative way,the most critical state and phenomena that could occur in the host rock.The PRACLAY gallery was excavated at the end of 2007;the heating phase will begin in 2010 and will last for at least 10 years.The PRACLAY gallery itself leaves an opportunity to study the possibilities of sealing a disposal drift in Boom clay and testing the feasibility of hydraulic cut-off of any preferential pathway to the main access gallery through the excavation damage zone（EDZ） and the lining with a seal in a horizontal drift（horizontal seal）.Indeed,this is a generic problem for all deep geological disposal facilities for HLW.An annular seal made of compacted swelling bentonite will be installed in the front of the heated part of the PRACLAY gallery for these purposes.This paper provides detailed considerations on the thermo-hydro-mechanical（THM） boundary conditions for the design of the PRACLAY heater test and the seal test with the support of numerical calculations.It is believed that these important items considered in the PRACLAY heater test design also constitute key issues for the repository design.The outcome of the PRACLAY heater test will be an important milestone for the Belgian repository design.
