三轴搅拌桩的工艺参数对其止水效果具有很大的决定作用.针对具有较厚的砂砾层及岩面较高的复杂地质条件,采取措施控制三轴搅拌桩的止水效果,并对影响三轴搅拌桩成桩效果的搅拌方式、水泥量、水灰比,采用L9(33)正交试验设计试桩,通过钻芯检测法对试桩的结果进行检验,在保证止水效果的前提下,选择经济性较好、施工速度较快的工艺参数.%The process parameters of the triaxial mixing pile have a great decisive effect on its water stopping effect. In view of the complicated geological conditions with thick gravel layer and high rock face, measures are taken to control the water stopping effect of the three-axis mixing pile, and the mixing method, cement amount and water-cement ratio affecting the pile-forming effect of the three-axis mixing pile are affected. The test piles were designed by L9 (33) orthogonal test. The results of the test piles were tested by the core test method. Under the premise of ensuring the water stop effect, the process parameters with better economy and faster construction speed were selected.
