摘要
高压旋喷桩常用于地基加固,但目前国内外旋喷桩施工经验较少,同时施工中易受到地层物理性质、力学性质、埋深、地下障碍物等多种因素的影响。采用有限元方法就旋喷桩对被加固地基的影响进行仿真分析。从而为高压旋喷注浆技术在不同工况下的施工工艺参数的合理选择提供理论支撑。
The high-pressure jet grouting piles have been used in foundation reinforcement commonly, but there was less construction experience of high-pressure jet grouting pile in domestic and foreign presently, on the other hand the construction was easily be affected by strata physical properties, mechanical properties, depth, underground obstructions and other factors. In this paper,the finite element method has been used to simulate the affection on reinforced foundation of jet grouting pile. Then theoretical support for a reasonable parameter choice has been provided to high-pressure jet grouting technology in different conditions of the construction process.
