| dc.description.abstract | 為研究求得代表現地Su值之方法，本研究收集台北盆地內工程災變案例，利用路堤填築破壞與深開挖隆起破壞案例資料，反算台北粉土現地平均不排水剪力強度Su(in-situ)，並與室內Su(UC)試驗值比較，得出以無圍壓縮試驗強度估計現地不排水剪力強度之經驗關係。另外，亦收集樁載重試驗案例，推算達極限狀態之樁周單位摩擦應力，據以建立樁側單位摩擦應力與Su(UC)之比值關係α（即黏著係數，adhesion factor）隨Su值之變化關係。上述研究成果可供爾後於台北盆地進行黏土工程穩定分析選用不排水剪力強度之參考。 | zh_TW |
| dc.description.abstract | For sake of obtaining the most representative in-situ Su , failure cases of embankment and deep excavation are amassed to back calculate the average in-situ undrained shear strength Su(in-situ) of clayey soils in Taipei basin. After that, empirical relation of Su(in-situ) and Su(UC) from unconfined compression test is established. Furthermore, cases of pile load tests are also collected to deduce the ultimate unit friction along pile shaft. Variation of adhesion factor α ( defined as ultimate unit friction divided by Su(UC) ) with Su(UC) is derived. The results of this study can provide a useful guide to selection of undrained shear strength for stability analysis in soft clay engineering. | en_US |
