WebJun 23, 2024 · Abstract. The paper presents the comparative analysis of several piles for different pier locations of a bridge by employing in-situ deep foundations tests and in-situ soil tests. The focus of the paper is on the presentation of the reliability of solutions obtained using the Dynamic Load Test (DLT) for bearing capacity of deep foundations – piles. The …
WebBased on the gradation tests, soil showed very wide range of fine contents and gravel contents. Accordingly, to be able to study the correlation between N SPT and E PMT results, soil was divided into three groups based on the D 50 values which are reflected on the gravel contents as well. Table 1 and Fig. 3 present the three soil groups. WebThe raw data collected during the test consists of the pressure read on the gauge of the control unit and the volume read on the volume measuring device of the control unit. This …
