摘要/Abstract

摘要： 在植生水泥土基材组配模型的基础上,为探明水泥、改良剂、有机物料和有机肥对植生水泥土植生性能的影响,通过水泥、改良剂、有机物料和有机肥单因素配比试验,分析 4 种影响因子对植生水泥土植生性能的影响。结果表明:各因子对植生水泥土植生性能均有不同程度的影响,随着水泥用量的增加,植生水泥土的容重、紧实度和 pH 均逐渐增大,最大增幅分别为 7. 4%、51. 6%和 9. 6%,孔隙率逐渐减小,最大减幅为 4. 2%;改良剂在调节植生水泥土 pH 的同时,对植生水泥土有机质含量及速效养分均有不同程度的贡献,并且能有效改善植生水泥土的生物特性;有机物料和有机肥能很好地改善植生水泥土物理结构,提升植生水泥土养分水平,从而改善植生水泥土的植生性能。研究结果可为植生水泥土生态护坡的应用提供理论依据。

Abstract: On the basis of the vegetative cement-soil configuration model,in order to investigate the effects of cement, habitat material modifying agent,organic material and organic fertilizer on the vegetation performance of the vegetative cementsoil,the effects of four factors on the vegetation performance of the vegetated cement soil were analyzed through the single-factor proportioning test of cement,habitat material modifying agent,organic material and organic fertilizer. The results showed that each factor had different degrees of influence on the vegetation performance of the vegetative cement-soil,with the increase of cement dosage,the capacity,compactness and pH of the vegetated cement soil gradually increased,with the maximum increase of 7. 4%,51. 6% and 9. 6% respectively,and the porosity gradually decreased,with the maximum decrease of 4. 2%;While the amendment adjusted the pH of the vegetative cement-soil,it contributed to the organic matter content and quick-acting nutrients of the vegetative cement-soil to different degrees,and could effectively improve the biological characteristics of the vegetative cement-soil. The organic materials and organic fertilizers can improve the physical structure of the vegetative cement-soil and enhance the nutrient level of the vegetative cement-soil,thus improving the vegetative properties of the vegetative cement-soil. The results of this study can provide a theoretical basis for the application of ecological slope protection of vegetative cementsoil.
