 摘要
 自平衡试桩法是一种基桩静载试验新技术，是接近于竖向抗压桩实际工作条件的一种试验方法。它有效弥补和解决了传统试桩法难以解决的基桩承载力检测问题:如超大吨位试桩、水上试桩、斜桩，坡地和狭窄场地试桩方面的一些难题，并以装置简单、操作方便、不占用场地、省时省力、安全经济等优点，在国内己开始得到推广应用。
 本文以自平衡静载试验为基础，阐述了我国灌注桩的发展及目前常规静载荷试验方法，根据自平衡测试法在世界各地应用研究状况，对自平衡测试法的原理、试验装置、试验方法、荷载箱的埋置技术进行了归纳，并对荷载箱进行设计。包括对荷载箱的结构分析、技术要求分析，液压缸主要尺寸的确定，结构设计及荷载箱的各个部件装配密封等。
 最后，在全面总结文档工作的基础上，提出了本课题尚有待进一步深入研究的一些问题。

Load box's design

Abstract
 The self-Balaneed method is a new technology of foundation Pile static load test, vertical compression Pile is closer to the actual working conditions of a test method. It effectively compensates for the traditional test and solves difficult to resolve by the Pile foundation pile bearing capacity of questions: such as extra-  heavy test piles,water test piles，Piles ramps, narrow slope and the venues test pile some problems， and the installation of a simple, operation convenience，off-site，time-saving effort，security, economic and other advantages in the country have begun to be widely used.
 This article takes self-Balanced loading Pile test as a foundation，    elaborated the development of our country pouring pile and the present convention static load testing methods. According to the actuai study state of the self-Balaneed loading pile test, the Principle, the equipment, the test ways and the buried technology of loading box for self-Balanced loading Pile test has been summed up. And carries on the design to the load box. Including to analysis of load box's structure, analysis of Specification, main dimension determination of Hydraulic cylinder, design of Structural and each unit assembling , seal and so on.
 Finally，in the comprehensive summary paper work foundation，proposed that still waited for further thorough research some questions of this paper.
