两种单桩载荷试验成果的对比

传统的单桩载荷试验方法,如堆载法、锚桩法,都存在设备庞大、材料复杂及运输、安装等问题。美国80年代开展桩承载力自平衡法试验的研究,我国东南大学于1996年开始引进应用,并取得一定成果。该方法具有设备简单、省时、省力等优点。本文通过锚桩法与自平衡法两种试验成果的对比,说明自平衡法在工程中的实际应用及两种试验成果的差异。

Comparison of Load Test Between Two Kinds of Pile Foundation

Conventionally, there are two methods to do the load test of the foundation of piles. One is to heap load, and the other is to anchor piles. And both come across the difficulties of transportation and construction because of the large/heavy equipment and complicated materials. In 1980s, USA began to study on the self - balancing test method of load - bearing capacity. And, in 1996, this method was used by Southeast University of China, and good results were obtained. This method not only can simplify the equipment, but also can save time and economize labor. Through the comparison between the self - balancing test method and anchor piles test methods, this paper described the actual application in the project, and pointed out the differences between the results of these two test methods.
