| Popis: | 105 In 2016 the Taiwan Mino earthquake, resulting in Zeng Wenxi Rih-sin revetment, Jian-shan embankment serious damage, and caused the Tainan Wei-guan building collapsed, after the earthquake by experts and scholars to conduct by site inspection survey, the results show that the soil liquefaction caused by the disaster. At home and abroad, there are many structures or strata in the structure of the soil caused by soil liquefaction damage, such as the Japanese Hanshin earthquake caused serious damage to the structure of the river flood dike, more underground pipelines and other disasters occur. Therefore, countries are actively studying the control methods and construction methods of liquefaction of soils in relation to the structural load on the geological weak areas or the pipeline protection measures in the stratum. Soil liquefaction mainly occurs in the sandy soil area, the common characteristics are high in the formation of water content, due to external factors such as seismic force or other disturbed soil external force, can make the soil liquefaction phenomenon. In order to prevent the soil liquefaction or the soil after the occurrence of the improvement, the development of the improved method of up to several, the main improvement is to increase the soil stiffness, increase the site capacity and improve the soil shear wall and so on. In the improved way can be divided into increasing the density of the formation of soil strength, the formation of solidification and condensation, increase the excess pore water pressure disappearance, isolation or mitigation of soil deformation, reduce the groundwater level and other sites to improve the construction mode. This study is aimed at the more common control methods to carry out inventory analysis, to explore the advantages and disadvantages of different prevention and control of the characteristics of finishing, as a follow-up in the public works, private construction companies, design supervision and other advantages and disadvantages of reference, as a choice or design reference. |
