Development of Piled Geo-wall
The aim of this study is to develop a new type soil structure, Piled Geo-wall, which can be applied to diverse structures as substitute for concrete ones and contribute to reasonable and sustainable development of infrastructures. This study consists of several experiment studies, full scale static and impact loading tests and a dynamic centrifuge model test, and proposal of a simple design method that can reproduce the experiments' results. The experimental studies and the performance of the proposed structure have already published, hence, proposal of a simple design model and the reproducibility of the experiments' results with using the proposed design model are presented in this paper. The contents of this paper are concluded as follows: (1) Simple external stability model of Piled Geo-wall for practical design was proposed, (2) The practicability of the proposed design model was confirmed from good reproducibility of real responses obtained from full-scale static and impact loading tests, and a dynamic centrifuge model test, (3) In the response analysis on Piled Geo-wall in static load situation (a full scale static loading test), high reproducibility of interaction between pile and Geo-wall body by using the proposed design model was confirmed, (4) In the response analysis on Piled Geo-wall in seismic situation (a dynamic centrifuge model test), high reproducibility of the maximum response of pile and Geo-wall body deformation by using the proposed design model were confirmed, (5) In the response analysis on Piled Geo-wall in impact load situation (a full scale impact loading test) for design on rock-fall protection structure, an evaluation procedure on assumption of design static load from impact one was also proposed and its practicability was confirmed from good reproducibility of the maximum pile response by using the proposed procedure and design model The following issues, however, have to be studied to apply the proposed model to more wide condition of Piled Geo-wall, (1) Validity of the proposed model to design on larger scale (width, height) Piled Geo-wall than the test ones, (2) Practicability of the proposed model to the design on Piled Geo-wall with using steel-pipe pile or multiple rows' piles, (3) Improvement of static load conversion procedure from impact one as being able to apply to diverse conditions of Piled Geo-wall.
