Development of an aseismic reinforcement of existing houses with bacteria

本研究以既有房屋的抗震加固为目的，对利用细菌改良土的力学特性进行了研究。在几种工况下进行了一系列三轴压缩试验。同时考察了一种细菌和一种土壤对改良土壤行为的影响。结果表明，细菌的种类对反应速率有影响，土壤的种类对改良土的抗剪强度无影响。与未改良土相比，改良土具有更高的抗变形能力。

In this study, mechanical characteristics of improved soil using bacteria were examined in order to develop the aseismic reinforcement of existing houses. A series of tri-axial compression tests was carried out under several conditions. Influences of a kind of bacterium and a kind of soil on the improved soil behavior were also examined. The results revealed that the kind of bacterium affected to a reaction rate and the kind of soil did not affect to the shear strength of improved soil. Comparing the no-improved soil, the improved soil has higher deformation resistance.
