Settlement Analysis of Piled-Raft Foundation Using Numerical Method

Abstract

The study gives an example of the sinking pier case at Takeda Interchange of National Highway NO.3 in Taiwan. We got the monitoring data, explored the impact on the consolidation settlement of piled-raft foundation from construction procedure and soil improvement by finite element method「Plaxis8.2」and predicted the degree of post-settlement. Analytic results are shown as follows：Firstly, the soil consolidation settlement model is built by the estimated soil parameters using the data of soil exploration. The calculation value of settlement and the measured value are identical. Secondly, soil improvement only shows effective in initial stage. The pre-consolidation settlement is smaller when building embankment is before pier than when building pier is before embankment.

Numerical Analysis of Bridge Caisson Foundation due to Riverbed Erosion

“…The bridge piers and soil data are cited the drilling data by the Taiwan directorate general of highways district maintenance office. Besides, they still refer to the results of [2,6,7] literature. The data is summarized as follows in Table 3.…”
