Improvement method for weakening collapsibility of loess of foundation
The invention provides an improvement method for weakening collapsibility of loess of a foundation, and belongs to the technical field of soil improvement. The technical problem to be solved by the invention is that a simple and effective improvement method for collapsible loess does not exist at present. The improvement method mainly comprises the steps of crushing, bentonite laying, mixing and rolling, and a control process including the addition amount of the bentonite and the water content of the mixed soil material is determined. After the foundation soil is treated, the wet collapsibility of a soil body can be effectively reduced, the anti-permeability of the soil body is enhanced, and the water stability coefficient of the soil body is improved, so that the strength of the soil body can be effectively improved. Compared with a traditional soil body improvement method, the method has the advantages that the construction is convenient, the construction period is relatively short, the construction cost is reduced, and the economic benefits are improved.
本发明提供了一种减弱地基黄土湿陷性的改良方法，属于土壤改良技术领域。本发明解决的技术问题是针对湿陷性黄土，目前还没有简单有效的改良方法。本发明改良方法主要包括破碎、摊铺膨润土、拌和、碾压的步骤，确定了包括膨润土的添加量以及混合土料含水率在内的控制工艺。本发明地基土经处理后，可有效降低土体的湿陷性，增强土体的抗渗性，提高了土体的水稳定性系数，从而可以有效提高土体强度，相较于传统的土体改良方法，本方法施工方便，施工周期相对较短，节约施工成本，提高了经济效益。
