摘    要:通过人工挖孔桩后压浆技术在抚州市某商住楼工程中的应用,分析对比了灌注桩后注浆单桩竖向承载力的提高幅度以及承载力估算值与实测值的差别,揭示了钻孔灌注桩桩底后注浆在竖向荷载作用下的承载性状及桩侧、桩端阻力发挥特性,并提出了工程桩的设计、施工建议,以期指导实践。

关 键 词:人工挖孔桩  后注浆  单桩承载力  注浆参数

Abstract:Through the application of artificial dig-hole post grouting pile technique in a commercial apartment engineering in Fuzhou city,this thesis analyzes and compares the raising range of post grouting single pile vertical bearing capacity and difference of bearing capacity estimation value and actual measuring value,demonstrates bearing features of cast-in-situ bored post grouting pile under vertical load function,and displaying features of side-piles and end pile resistance,and then puts forward the design and construction proposals of engineering piles,so as to guide practice.
Keywords:artificial dig-hole pile  post grouting  single pile bearing capacity  grouting parameter
