（中國建筑科學(xué)研究院地基所 北京 100013）[提要] 支護結(jié)構(gòu)圈梁的空間效應(yīng)對支護樁的變形和內(nèi)力有著重要影響。根據(jù)圈梁對支護樁的約束和變形協(xié)調(diào)，給出一種考慮圈梁協(xié)同作用的支護樁的簡化計算方法，并結(jié)合實測資料進行了對比分析。
[關(guān)鍵詞] 支護樁 圈梁 空間效應(yīng) 彈性地基梁It is proved that the spatial effect of ring beam has significant influence on the deformation and stresses of retaining piles. Based on the deformation coordination of ring beam and piles, a simplified method considering the spatial effect of ring beam is presented to analyse retaining piles. The calculation results are also comparied with the measured ones.
