Fundamental Study on Response Properties of Structures Constructed on Lunar Regolith 査読

The Artemis Program, for constructing the lunar base, is in progress. How to design and construct architectural and civil engineering structures in the lunar environment has become an important issue. The lunar surface is covered with soft sand, called regolith, and it is required to protect lunar bases and structures, as well as internal precision equipment, against vibrational disturbances such as moonquakes and meteorite collisions. Therefore, in this study, the static and cyclic triaxial compression tests of the regolith simulant were
conducted. The reference strain and equivalent damping factor of the regolith simulant were smaller compared to sandy soil on Earth. In addition, a shaking table test using model specimens was conducted on the response properties of regolith ground alone and structures set on regolith ground. The buried foundation and pile foundation notably suppressed the horizontal response
attributed to the rocking component compared to a direct foundation.

Seismic response and nonlinear characteristics of pile-soil springs in structures supported by pile group in granular soil on sloping bedrock 査読

In places prone to earthquakes, piles need to be designed to resist seismic damage. However, the characteristics of the soil significantly impact the seismic resistance of piles. Accordingly, in this study, shaking table tests and three-dimensional finite element analyses were conducted to investigate the seismic response and nonlinear characteristics of pile-soil springs of a structure supported by a pile group in granular soil on a sloping bedrock. The analytical experiments and simulation were conducted on a group of nine piles arranged in the shape of a square. The results showed that the constraint condition at the pile tip influenced the bending moment response of piles during large input motion, such as that observed during earthquakes. Furthermore, the pile location, direction of pile displacement, and depth was found to affect the influence of the sloping bedrock on the pile soil springs.

In order to study seismic response properties and interaction mechanism of a frozen soil-structure dynamic interaction system in liquefiable soil, two shallow foundation structures with different natural frequencies were designed. By performing small-scale shaking table tests, dynamic response characteristics of two shallow foundation structures with different natural frequencies under seismic action were investigated in different freezing depths of the artificial-made frozen soil, and then a nonlinear finite element program was used to establish the dynamic coupling nonlinear calculation model of frozen soil-superstructure considering the gradient change of frozen soil stiffness and the inertial interaction of the superstructure, and the seismic response mechanism of frozen soil-structure nonlinear interaction system under the horizontal seismic excitation was explored further. The results show that the ground freezing restrains the seismic response of ground surface in some degree while increasing the seismic response of superstructure due to the decrease of interaction between frozen soil and structure, especially for the structure with a high natural frequency. Thus, the predominant period of ground, the dynamic characteristics of superstructure, the kind of seismic wave and the liquefaction degree of ground have great influences on the seismic response of a structure. Therefore, more attention should be paid to the influence of frozen soil on dynamic characteristics of a structure in frozen soil regions.

This study explored the seismic response of a house supporting base sides with a polymeric displacement control material and by magnetically levitating the foundation base. In this paper, we explore the possibility and efficacy of a seis-mic-isolated detached house as described above from both a shaking table experiment of model and three-dimensional finite element analysis. The seis-mic-isolated model showed stable response and its acceleration response was significantly reduced compared to the base-fixed model in the shaking table test. Three-dimensional finite element analysis was possible to simulate the experimental results. In the seismic response analysis of a full-scale detached house, the seismic-isolated model showed response reduction and its residual displacement was smaller than that of the sliding-base isolation model.
