斜樁群 的英文怎麼說
中文拼音 [xiézhuāngqún]
斜樁群
英文
batter pile cluster-
The model is called " generalized elastic theory " in this paper, which can take the plastic behavior of the soil around the pile into account, and also can analyze the battered pile and pile group
這種方法可以考慮樁周土的塑性和樁-樁相互作用，還可以分析斜樁以及有斜樁的群樁。把廣義彈性理論法用於單樁分析，建立了相應的模型和公式。Battered pile and pile group are generally used in bridge, wharf and foundation of transmission power
斜樁以及有斜樁群樁廣泛應用於橋梁、碼頭以及大型輸電線路基礎等。There is less research about bartered pile and pile group. in this paper the " generalized elastic theory " is proposed to solve the problem
目前對于斜樁單樁和有斜樁群樁承載特性的研究，還鮮有文獻報道。Under the vertical load, the vertical pile group has bigger bearing capacity than the battered pile group. under lateral load, the positive battered pile group has bigger bearing capacity than the vertical and negative battered pile group. both model experiments and prototype experiments are conducted
與單樁類似，豎向受荷直樁群樁承載力比斜樁群樁大；水平受荷群樁， 「正斜」單樁組成的群樁比直樁群樁和「負斜」單樁組成的群樁的承載力大。The model experiments results indicate that the pile group composed of extending all around piles can bear inclined load better. this is beneficial to the foundation of transmission tower. the prototype experiments results indicate that the micropile ' s load capacity is satisfied with design
模型試驗發現，伸向四周的單樁組成的群樁具有更好的抵抗傾斜荷載的能力，這一點特別有利於輸電線路基礎等；原型試驗發現，微型樁單樁和群樁的承載力完全達到設計承載要求，其群樁效率在0 . 9左右。Secondly, considering the complexity of the analysis of inclined - loading pile, nonlinear finite element method is adopted to calculate the internal force and displacement of pile group under inclined loads, with the concept of equivalent width presented to simplify 3d problems into 2d problems. and a program is developed as well, which is able to consider the continuity, elastic - plasticity and layered characteristic of soil around the pile shaft. besides, the interactions among pile, base slab and soil are considered in this program and contact surface element is used to simulate slipping and crazing between pile and soil, or between base slab and soil under loads. then, the non - tension analysis is proposed, to reflect the low - tensile property of soil and concrete
在此基礎上，針對傾斜荷載下群樁基礎分析中的復雜性，提出採用非線性有限元對傾斜荷載下群樁的內力及位移進行分析，應用樁的等效寬度概念將空間問題簡化為平面問題考慮，並開發出能考慮樁周土介質連續性、彈塑性、分層性等因素的傾斜荷載下群樁內力及位移分析的計算機程序，並在程序中考慮了樁、土、承臺的相互作用，提出了採用接觸面單元來考慮荷載作用下樁與土體及承臺與土體間的滑移、開裂；並在此基礎上，提出了傾斜荷載下群樁基礎的「無拉力」分析方法，可有效地反映土體及混凝土材料的低抗拉特性。According to the current codes, piles under inclined loads top are analyzed respectively under axial and lateral loads with the results superposed, in which inaccurate error is inevitable. focusing on this point, the analysis of pile and pile group under inclined loads are thoroughly discussed in this article
本文針對我國現行規范將樁頂傾斜荷載分解為豎向和水平荷載分別計算再進行迭加而存在的計算誤差較大的不足，對傾斜荷載下基樁及群樁的受力分析進行了深入的探討。分享友人
