摘　　要：在建筑工程中，粉喷桩可用于加固深层地基。研究了桩土置换率、水泥土龄期、加固材料，搅拌时间，天然土的含水量以及掺和料对粉喷桩强度的影响规律，探讨了粉喷桩和桩间土的力学性能。粉喷桩成功地应用于东营地区，具有施工简单，承载能力相对较高的特点，适合于粘土。Cement powder guniting pile can be used to consolidate ground foundatiion.The consolidation strengthe is related with dimension of piles ,such as length,diameter,distance and distribution of piles.The replacing ratio between piles and soils, cement ages, consolidation materials, stirring time, water content of natural soil, and mixing material have some effects on the strength of the cement powder guniting pile . The mechanical property of the cement powder guniting pile and the soils for stablizing piles is studied. Successful applications of cement powder guniting pile in Dongying area show that cement powder guniting pile has high bearing capacity and can be easily constructed.
