锤击贯入试桩法是一种新型的快速试桩法,已于1981年10月通过部级鉴定,被确认为是我国桩基工程测试方面的一项有发展前途的适用新技术。几年来我们先后在天津地区进行了24项工程133根桩的锤击贯入试验,其中20项是确定单桩承载能力,供设计部门使用。4项是属于检验桩基质量,均取得了较好的技术经济效果(表1、图1)。 The hammer penetration penetration test pile method is a new type of rapid test pile method. It passed the ministerial level appraisal in October 1981 and was confirmed as a promising new technology for testing pile foundation engineering in China. In the past few years, we have carried out hammer penetration tests of 133 piles in 24 projects in Tianjin, of which 20 are for determining the bearing capacity of single piles for use by the design department. The four items belong to the quality of test piles, and all have achieved good technical and economic results (Table 1, Figure 1).
