Method for measuring opening amount of circular seam of duct piece in assembly type open caisson construction
The invention discloses a method for measuring the opening amount of a duct piece circular seam in assembly type open caisson construction, which comprises the following steps of: calculating the total side wall frictional resistance Tf of the side wall of an annular duct piece and each soil layer according to the actual limit frictional resistance standard value fkx of the side wall of the annular duct piece and each soil layer and the thickness Hi of each soil layer; according to the relation between the height H of the side wall of the open caisson in soil and the excavation depth d of the open caisson, the blade foot counter-force R of the side wall blade foot of the annular pipe piece is calculated; the total stress F of the circular seam bolt is calculated according to the gravity G borne by the circular seam bolt, the reverse acting force N, the side wall frictional resistance Tf and the blade foot counter force R; and according to the stress F of the circular seam bolts, the circular seam opening amount delta x between the adjacent circular pipe pieces is calculated. And accurate measurement of the opening amount of the circular seam is realized.
本发明公开了一种装配式沉井施工中管片环缝张开量的测定方法，包括：通过环管片侧壁与各土层的实际极限摩阻力标准值fkx和各土层厚度Hi，计算环管片侧壁与各土层的总的侧壁摩阻力Tf；根据土中沉井侧壁高度H和沉井开挖深度d的关系，计算环管片侧壁刃脚的刃脚反力R；根据环缝螺栓受到的重力G、反向作用力N、侧壁摩阻力Tf、刃脚反力R计算环缝螺栓的总的受力F；根据环缝螺栓的受力F计算得到相邻环管片之间的环缝张开量Δx。实现对环缝张开量的精准测定。
