(同濟(jì)大學(xué)滬西校區(qū)鐵建系 上海200331)[提要] 鉆孔咬合灌注樁作為一種新的基坑圍護(hù)結(jié)構(gòu),克服了傳統(tǒng)樁在基坑圍護(hù)結(jié)構(gòu)中防水性能差的缺點,在地鐵車站基坑圍護(hù)中得到采用。對該圍護(hù)結(jié)構(gòu)灌注樁承受的彎矩提出按剛度分配的計算方法,通過幾次迭代計算后,得到各灌注樁與自身剛度成正比的彎矩值。

For the bending moment calculation of clutching borehole grouting pile, a method based on rigidity distribution is proposed. After several iteration calculations, the bending moment of different piles is calculated proportional to its rigidity.
