模袋固化土室内配比试验

Lab experimental research on solidified soil mixing ratio

为了了解模袋固化土强度增长规律,通过对现场原状土的物理分析及模袋固化土的室内配比试验,选择合适的固化剂和掺入比,并建立了贯入阻力、无侧限抗压强度与龄期的关系,为利用模袋固化土作为堤心来替代砂石料等常规材料修建海上围埝提供了理论依据,从而确定模袋固化土充填围埝的可行性,并为现场施工提供了经济合理的配合比。在实际应用中,采用模袋固化土施工,可降低工程造价成本,使资源配置合理化,同时也达到环保的效果,降低废料污染。

To grasp the law of strength increase of geotextile bags filled with solidified soil increased bag rule,through the on-site physical analysis of undisturbed soil and lab proportion test,we chose a suitable curing agent and mixing ratio,and the established the relation of the penetration resistance and unconfined compressive strength with the age,to provide a theoretical basis for the use of geotextile bags filled with solidified soil as the embankment core instead of the conventional materials such as sand and gravel for sea dyke construction,and provides an economical and reasonable proportion for the site construction.Through the application of geotextile bags filled with solidified soil,we can cut down the cost,realize rational allocation of resources,and protect the environment.
