摘　　要：抚州市临川区嵩湖乡辖区嵩湖堤除险加固工程射水造墙施工过程中主要面临造孔孔壁稳定的技术难题。在简述工程概况的基础上,从造孔过程控制、射流口紊流控制、泥浆固壁及地下水位影响等方面对孔壁稳定控制问题进行了分析探讨。结果表明,射水造墙主要由造孔技术和水下混凝土浇筑技术两部分组成,其中孔壁稳定是成孔的关键。通过加强造孔施工参数控制,提升不同施工阶段泥浆性能,根据地下水位控制泥浆密度等措施的应用,以取得较为理想的射水造墙加固施工效果。In the construction process of water jetting wall in Songhu Dike Reinforcement Project in Songhu Township, Linchuan District, Fuzhou City, the main technical problems of hole wall stability are encountered. On the basis of summarizing the general situation of the project, the problems of hole wall stability control are analyzed and discussed from the aspects of hole making process control, jet inlet turbulence control, mud wall consolidation and the influence of groundwater level. The results show that the water jetting wall is mainly composed of two parts of the hole making technology and the underwater concrete pouring technology, in which the stability of the hole wall stability is the key to the hole forming. By strengthening the control of construction parameters, improving the mud performance in different construction stages, and controlling the mud density according to the underground water level, the ideal construction effect of water jetting wall reinforcement can be achieved.
