静压灌浆和高压旋喷注浆技术处理软弱地基

On treatment for poor subsoil with static pressure injection and high pressure jet grouting

介绍了静压灌浆和高压旋喷注浆的理论及作用机理,探讨了静压灌浆和高压旋喷注浆处理技术相结合的方式,结合实际工程案例,研究了对码头岸坡软弱地基进行加固处理并控制基础沉降的加固机理、施工工艺和应用效果,提出的思路和施工方法对软弱地基的加固处理工程具有一定的参考价值。

The theories and mechanism of static pressure injection and high pressure jet grouting are introduced in this paper,and the method based on combining static pressure injection with high pressure jet grouting is discussed.Along with the analysis of practical engineering project,the mechanism of strengthening for poor subsoil in bank slope located in wharf and control of foundation settlement,construction technology and application effect are studies.The presented train of thought and the method of construction for strengthening of poor subsoil hold reference value.
