摘要

微生物诱导碳酸钙沉淀（MICP）技术是新兴的岩土工程绿色加固技术，在散粒土加固方面具有良好的应用前景。MICP加固砂土的均匀性和力学表现是目前存在的重要问题，为优化MICP加固方法，改善加固后砂土的综合表现，开展MICP加固砂土方法对比试验研究。详细介绍了传统两相法、pH法及温控法MICP加固方案，利用传统两相法、pH法及温控法开展砂柱试样的MICP加固试验，从加固试样的碳酸钙分布均匀性、反应液中钙离子利用率及加固试样的无侧限抗压强度等3个方面对比分析3种MICP加固方法的综合表现。结果表明：在试验条件下，传统两相法在3方面均表现最差；pH法和温控法整体表现较好，其中温控法反应液利用率较高，在高加固程度时强度略高，综合表现最优。

Abstract

Microbially induced calcium carbonate precipitation (MICP) is a new green ground improvement technique in geotechnical engineering and has a promising prospect in reinforcing granular soils. The uniformity and the mechanical performance of MICP-treated sands are important issues in the MICP method. To optimize the MICP-treatment scheme and improve the overall performance of MICP-treated sands

a comparative experimental study on different MICP-treatment schemes for sands was carried out. Firstly

the MICP-treatment schemes

including the conventional two-phase method

the pH method and the temperature-controlled method

were introduced in detail. Then

a series of MICP-treatment experiments on sand columns were conducted

following the three different schemes

respectively. Finally

the three different schemes were compared in terms of the distribution of CaCO

in the post-treatment specimens

the utilization rate of reaction solutions and the unconfined compressive strength of the post-treatment specimens. Under the testing conditions in this paper

the conventional two-phase method has the worst performance in the three aspects; the pH method and the temperature-controlled method generally perform well; in comparison with the pH method

the temperature-controlled method has a higher utilization rate of reaction solutions and a higher strength under high-treatment conditions; the temperature-controlled method has the best overall performance.
