摘    要:为使水平承载微型桩在工程中得到充分合理的应用,通过现场静载试验和有限元数值分析,对微型桩的水平承载特性进行了研究。现场载荷试验对比了不同桩长、不同抗弯刚度微型桩的水平承载特性;数值分析探讨了桩径、桩身模量等主要因素对微型桩水平承载特性的影响。研究认为,通过合理选择微型桩桩长、桩径以及桩身插设钢管等措施,可以提高水平承载微型桩的承载能力。

关 键 词:微型桩  水平承载特性  现场试验  数值分析

Abstract:In order to apply the horizontal bearing mini pile in engineering adequately and reasonably, the horizontal bearing performance of mini pile is studied through field static test and finite element numerical analysis. The horizontal bearing performance of mini piles with different pile length and flexural rigidity are compared through field load tests. The influence of the pile diameter, the pile modulus and other factors on the horizontal bearing performance of mini piles is discussed based on numerical analysis. Finally, it is summed up that the horizontal bearing capacity of mini pile can be enhanced by selecting reasonable pile length and pile diameter, inserting steel pipes in piles and other measures.
Keywords:mini pile  horizontal bearing performance  field test  numerical analysis
