为了确定单桩承载力,用静荷载试验办法是一种传统的可靠方法。但这种方法笨重、费时、费钱;试验过的桩一般即以报废处理;试验桩是事先确定的,施工时比较重视,加之现场地质地层的复杂变化,其试验所得成果的代表性也受到影响,这使桩基静载荷试验在工程实践中受到限制。为了寻找 In order to determine the bearing capacity of a single pile, the static load test method is a traditional and reliable method. However, this method is cumbersome, time-consuming and costly; the tested piles are generally treated as scrapped; the test piles are pre-determined, the construction is more important, and in addition to the complex changes in the on-site geological formation, the results of the test are also represented. Impact, which makes the pile static load test limited in engineering practice. To find
