［摘要］以南京市某單管塔鋼管樁為例，根據(jù)《建筑樁基礎(chǔ)技術(shù)規(guī)范》（JGJ 94—2008）計算橫向荷載作用下樁頂側(cè)移、轉(zhuǎn)角、樁身最大彎矩、樁底土壓力等，并且運用SAP2000軟件計算比較兩種結(jié)果的差異和相似性，同時放大鋼管材料的彈性模量模擬剛性樁，配合理論計算，將剛性樁結(jié)果與彈性樁結(jié)果比較得到兩者差異性，為同類工程的設(shè)計以及校核提供參考。

Abstract:Combined with the steel pipe pile foundation of communication monopole in Nanjing, the top lateral displacement, bending angle, maximum bending moment of the pile and the basal soil pressure were calculated under lateral load according to Technical code for building pile foundations（JGJ 94—2008）.The difference and similarity of two kinds of results calculated by SAP2000 were compared. The Young′s modulus of the steel material was magnified to simulate rigid pile with the theoretical calculation and the results of elastic pile and rigid pile were compared to obtain the difference of two piles, which can provide references for design and check the similar engineering.
Keywords:monopole; top lateral displacement; soil pressure; pile foundation; elastic pile; rigid pile
