摘要
国内外的试验研究和工程实践表明,对钻孔桩进行后压力灌浆加固能够有效地提高桩的承载力。近年来,钻孔灌注桩后压浆工艺的广泛应用,使得桩身承载力大幅提升,达到以有限的桩长满足较高的承载力的要求。施工难度降低,质量易于控制,成本降低,有着良好的经济效益和发展前景。
The domestic overseas test research engineering practice showed the post grouting reinforcement for bored pile can effectively improve its bearing capacity.In recent years,the post grouting technology for bore pile was applied widely,and made a great improvement of pile bearing capacity,so that the pile with limited length can meet the requirement of higher bearing capacity.By this method,construction difficulty cost can be reduced and quality is easily controlled.Therefore,it will have the great economic benefits and development prospect.
