group action of piles 中文意思是什麼
group action of piles
解釋
群樁作用-
As the pile group with variant pile diameters and pile lengths differs in composition from the conventional pile group with identical single piles, the combined action of engineering piles and fender piles is most important for mechanism of the technique of one pile with three usages
由於樁長、樁徑不同的樁組成的群樁與傳統的由幾何條件相同的樁組成的群樁在構成的形式上有所不同，因此圍護樁與工程樁共同作用理論是「一樁三用」技術中需要重點研究的內容。 -
Correlative function method and variable function method are used to calculate the relevant range of soil layer. the limit capacity of bored pile is determined by the cone penetration tests ( cpt ) and the static loading tests and related statistics parameters are also evaluated. considering the effects of group piles, the action effect is calculated by the settlement of pile foundation and the reliability index of single pile as well as group piles is determined by monte - carlo method
本文選擇臨近場地的四座高層建築地基的全部勘測資料，以沿深度方向的一維平穩高斯隨機場作為樁基土層土性參數的數學模型，利用相關函數法和變異函數法計算土層的相關范圍，由cpt和靜載試驗結果綜合確定鉆孔灌注樁的極限承載力，進而對相同場地各試樁的承載力進行折算后檢驗其概率分佈，並估計有關統計參數：考慮群樁效應確定樁基承載力，由樁基沉降反算其作用效應，由monte - carlo方法計算單樁及群樁的可靠指標。
