expansion-pressure test
解釋
膨脹壓力試驗-
Comparing their expansion force counted by liner interpolation, the author puts forward the critical value existing in the reinforcement ratios. in the meantime, the tri - axial shear test of cu on the expansive soils and reinforced soils under different compactness, layers and confinement pressure are finished. it is concluded that the cohesive force of reinforced soils is greater than that of expansive soils, moreover the internal friction of reinforced soils is equal to that of expansive soils
同時對膨脹土及其加筋土分別進行了不同壓實系數、加筋層數及周圍壓力下的三軸固結不排水剪切試驗，分析這三種因素對素土和加筋膨脹土強度的影響，比較加筋前後膨脹土的c 、值，得到c值增加值幾乎不變的結論。 -

In order to fully develop the theory of squeezed branch piles, in particular, the justification of its superior performance in terms of the bearing capacity and sinking displacement, we have derived the analytical formulas of the axial load and the strain at arbitrary depth ; based on existing static loading test results and research on belled pile, together with the analysis of on - site testing data, we have applied the expand theory on sphere holes to the computation of radial stress of squeezed branch piles under hole expansion ; taking the oil pressure of hole expansion in to account, we have find the a branch force under certain hole pressures, hence we can estimate the maximum bearing capacity of single piles ; we have introduced the experiential formulas for the bearing capacity of squeezed branch piles based on its stress characteristic and pile testing data ; we have also done numerical simulations of squeezed branch piles utilizing finite element method software ansys ; we have matched the simulation res ults with those of on - site basic load experiments, regenerating the distributions of stress fields and strain fields of squeezed branch piles, and from those distributions, we can determine the optimal distances between plates and piles
為了完善支盤樁的設計理論，探求支盤樁高承載力和低沉降量的內涵，本文推導出了支盤樁任意深度的截面荷載以及位移隨深度變化的理論公式；基於已有的靜載試驗成果及有關擴底樁的研究成果，從對現場測試數據的分析，將球形孔擴張理論引入到支盤樁擴孔時徑向應力的計算，考慮到擴孔時的油壓數據，求得某一孔壓下的支盤力，據此估算單樁極限承載力；同時根據對支盤樁的受力特點和試樁數據的分析，提出了支盤樁承載力計算的經驗公式；用有限元分析的方法，利用大型有限元分析軟體ansys對支盤樁進行數值模擬，並將模擬結果同現場的靜載試驗結果進行對比，再現了支盤樁在荷載作用下土中應力場和位移場的變化，根據應力場和位移場的變化范圍，指出最佳盤間距和樁間距；為支盤樁的設計和施工提供了一個可量化的設計依據。 -
