Standard test methods for measurement of hydraulic conductivity of saturated porous materials using a flexible wall permeameter
使用撓性壁滲透計測量飽和滲透性材料水滲導性的標準試驗方法Along with the progress of drilling technology, many new types of bha such as steering motor assembly, dropping assembly with eccentric bend sub, dropping assembly with flexible connection are developed based on common building, dropping and holding assemblies. for using these bha, a new mathematical model is put forward for 3d static analysis of these types of bha under small deflection. and its weighted residual solution is given. the mathematical model includes ( 1 ) differential equations ; ( 2 ) boundary conditions at drill bit, stabilizer, bend angle, diameter change, tangential point and borehole wall ; ( 3 ) lateral forces and deflection angles of bit. the software based upon this method runs well
為了更好地應用各種新鉆具，建立了適用於對普通下部鉆具、導向鉆具、帶偏心彎接頭和柔性接頭的下部鉆具進行三維小撓度靜力學分析的數學模型，包括（ 1 ）微分方程； （ 2 ）鉆頭、穩定器、彎角、變截面、切點和井壁的邊界條件； （ 3 ）鉆頭的側向力和鉆頭轉角.給出了該模型的加權余量解.用該方法編寫的軟體應用效果良好Nowadays, the pcc pile have been widely used for soft ground improvement and application of foundation engineering. the behavior of pcc pile, that subjected to lateral load has been studied in this paper. the behavior of the pcc pile has involved moment and horizontal displacement and load of pcc pile. they are studied by in the physical model experimen, field test finite element numerical analysis, and exponential progression solution. in additional, the comparatively computal analysis are carried out among pcc pile, cast - in - situ concrete circular pile, prefabricate concrete square pile, and obtain some signification conclusion
本文主要圍繞現澆混凝土薄壁管樁（以下簡稱pcc樁）這一新型的樁基結構型式的水平承載性狀展開研究，通過室內模型試驗、現場試驗、有限元數值模擬分析試驗及彈性冪級數解析法分析等手段，對pcc樁水平承載的樁身受力性狀，樁身撓曲位移，樁身彎距分佈，樁與樁周土相互作用的地基反力等幾方面進行了初步的探討和研究，最後將pcc樁與目前工程中的兩種常用於承受水平荷載的樁型進行對比計算分析，得到有意義的結論。
