《岩土工程学报》１９９８年第４期所载“大直径泥质软岩嵌岩灌注桩的荷载传递性状”一文（作者刘松玉等，以下简称“刘文”），提供了许多宝贵资料。笔者对刘文分析整理后，取其部分绘成系数ξｐ与嵌岩比关系数图（图１）。ξｐ＝ｑｍａｘ／ｆｗ，式中ｆｗ资料来源於文献［１ The article “Load Transfer Characteristics of Large-diameter Muddy Soft Rock Embedded Cast-in-place Piles” (author Liu Songyu et al., hereinafter referred to as “Liu Wen”) contained in Journal of Geotechnical Engineering, No. 4 of 1998 provides a lot of valuable information. After analyzing and arranging Liu Wen, the author took part of the plot of the relationship between the coefficient ξp and the ratio of inlaid rock (Figure 1). Ξp=qmax/fw, where fw data is from literature [1
