一、前言 荷兰工程师Van der Veen于1953年提出了一种根据静载试验资料确定单桩极限承载力的方法。该方法在国际上受到了重视,从土力学和基础工程文献中常可见到。在我国,该方法被称之为“对数百分率法”(以下简称百分率法),并得到应用。在广东地区,该方法已成为根据检定性试验成果推算单桩极限承载力P_极的三种常用方法之一。有的 I. INTRODUCTION In 1953, the Dutch engineer Van der Veen proposed a method to determine the ultimate bearing capacity of a single pile based on the static load test data. This method has received international attention and is often seen in the soil mechanics and basic engineering literature. In our country, this method is called “the fractional rate method” (hereinafter abbreviated as percentage method) and applied. In Guangdong area, this method has become one of the three commonly used methods for deriving the P_ pole of the ultimate bearing capacity of a single pile based on the test results. some
