水泥土搅拌桩作为一种良好的软弱地基处理方式,对软土地基进行加固,能最大限度利用原状土的承载力,在地基处理工程中应用广泛。本文以某项目为研究背景,从该项目的地质特征、地基处理方案比选、材料选定及配合比设计、试桩、优化、大面积成桩、检测及工后评定等方面进行阐述,对在大面积软弱盐碱地上进行水泥土搅拌桩地基处理进行深入分析和论述,对其可行性、经济性和总体效果进行评价,旨在指导同类项目的施工。
Cement-soil mixing pile is a kind of good weak foundation treatment method, which can reinforce the soft soil foundation and can make full use of the bearing capacity of undisturbed soil. It is widely used in foundation treatment engineering. In this paper, a project as the research background, from the geological features of the project, comparison and selection of foundation treatment options, material selection and mix design, test pile, optimization, large area pile, testing and post-assessment and so on, The ground treatment of cement-soil mixing piles on a large area of soft saline-alkali soil is conducted in-depth analysis and discussion, and its feasibility, economy and overall effect are evaluated to guide the construction of similar projects.
