高含水量软土地基水泥土桩成桩质量试验研究

Trial Study on Cement-soil Piling Quality in Soft Soil Foundations of High Water Content

针对淮盐高速公路淮安段高含水量软土地基的工程地质特性 ,依据设计文件进行水泥土搅拌桩成桩质量的现场试验研究 ,提出采用增强剂 (石膏 )和减水剂 (木钙 )作为水泥土搅拌桩的外加剂 ,以保证水泥土桩的成桩质量。提出了保证成桩质量的控制管理措施。

To the engineering geological characteristics of the soft soil foundations with high water content in Huaian segment of Huaian to Yancheng Freesway,a spot trial study on the quality of cement-soil piles is conducted in accordance with the designed document.The use of Intensifier (gypsum) and dewatering agent (lignin) are brought forward in the text to serve as additives to secure the piling quality of cement-soil piles.Finally,the controlling supervision measures for guarding the piling quality are also raised in the text.
