摘要

摘要提出了一种类似于自然过程的创新技术,即生物地球化学(碳酸盐)成岩作用,以建造混合堤防。在本研究中,混合路堤被定义为在软土基质中具有微生物诱导的砂片和柱的框架结构的土质路堤。砂型材料由解尿菌诱导的镁方解石或白云石胶结而成。为了设计和建造混合堤防,基本问题,如稳定性方面的可行性,地质环境工程实践等,进行了检查和讨论。结果表明,混合路堤既环保,又有助于解决实际工程中遇到的技术和资金问题。

Concept of hybrid embankment
Abstract An innovative technique which is similar to a natural process, i.e., biogeochemical (carbonate) diagenesis, is proposed to construct a hybrid embankment. In this study, the hybrid embankment is defined as a soil embankment which has a microbially induced framework structure of sand sheets and columns in the soft soil matrix. The sand materials are cemented with magnesium-calcite or dolomite, induced by ureolytic microbes. To design and construct hybrid embankments, fundamental problems, such as feasibility in terms of stability, geoenvironmental engineering practices, etc., are examined and discussed. It was shown that the hybrid embankment can be environmentally friendly and also can contribute solving technical and financial problems encountered in actual practice.
