采用旋喷桩法加固软弱地基,在我国已经得到越来越广泛的应用。然而,旋喷桩的设计计算,目前尚无规范可循,因此统一设计方法和计算参数乃是从事旋喷工作者的迫切任务。本文对旋喷桩的设计计算方法进行了总结。文中引用了有关单位的一些资料,对此深表谢意。关于旋喷桩的设计工作步骤,本文拟从以下五个方面进行讨论。最后,以具体的工程实例加以说明。 The use of jet grouting piles to reinforce the soft foundation has been applied more and more widely in China. However, the design calculation of jet grouting piles has not yet been followed by regulations. Therefore, the unified design method and calculation parameters are the urgent tasks for rotary jet grouting workers. This paper summarizes the design and calculation methods of jet grouting piles. The article quoted some information from the relevant units and thanked them very much. With regard to the design work steps of jet grouting piles, this paper intends to discuss the following five aspects. Finally, a concrete project example is used to explain.
