Based on elastic methods , the single pile behavior is studied through mindlin stress solution , followed by the analysis of interaction between two piles . thus , the interaction factor is obtained , based on which the interaction between more piles in pile group can be considered using superposition principle 本文以彈性理論法為基礎(chǔ),首先運(yùn)用mindlin應(yīng)力解對單樁進(jìn)行分析,然后分析了兩根樁時(shí),樁與樁之間的相互影響,最后根據(jù)彈性理論疊加原理,通過引入一個(gè)“共同作用系數(shù)” ,擴(kuò)展到群樁中去。
