自平衡测桩法的适用性讨论

自平衡测桩法是高承载力条件下较为有效的桩基极限荷载检测手段之一。自平衡测桩法的荷载箱形式主要分为等截面荷载箱和变截面荷载箱两种,本文从这两种形式的工作机理加以论述,并就自平衡测桩法的适用性进行讨论,自平衡测桩法如同其他桩基础极限荷载检测方法一样,有一定的局限性,因此必须在使用中认真研究桩基的承载力学特性,提高检测准确性,为桥梁桩基础的检测提供理论基础。

Discussion on the Applicability of Pile Self-balance Test Method

Pile self-balance test method is one of the effective pile foundation ultimate load test under the condition of high beating capacity. Its load cell form consists of uniform load box and variable cross- section load box. The article begins with working mechanism of these two forms and discusses the applicability of pile self-balance test. Since this method is limited like other methods of testing ultimate load of pile foundation, the load mechanical property must be studied seriously by using this method, improving detection accuracy, and providing theoretical foundations for bridge pile foundation detection.
