一前言对导流堤坡脚的鉄綫石籠設計,經过調查研究与現埸試驗,最近进行了一系列改进,通过某大桥施工实践,認为省工省料值得推广。这里所指整体石籠,是指一般常用矩形石籠。現介紹于后。由于笔者水平有限,有些問題体会不够,謬誤之处一定难免,希望大家指正。二概述过去石籠設計均参考有关书籍介紹,石籠长度一般为3～4m,但根据計算冲刷要求,石籠鋪設应有一定长度,例如10～15m,此时将几个石籠用缺綫束捆扎連接,此种石籠称之拼装石籠,该种石籠存在以下缺点:1.用料費,因为两个石籠纵向拼接处有两个横断面,因之横隔鉄綫多化了一倍。2.拼装石籠用鉄綫束捆扎,当石籠下垂时与纵向骨架受力主筋强度不一致,冲刷后部 A foreword To the shoal line shovel foot of the shilock design, after the investigation and the current test, recently conducted a series of improvements, through a bridge construction practice, that the provincial labor and materials worth promoting. The whole stone cage here refers to the commonly used rectangular stone cage. Now introduced later. Due to the limited level of the author, some problems are not enough to understand. Fallacies must be inevitable. I hope Members can correct me. Two over the past stone cage design refer to the introduction of books, gabion length is generally 3 ~ 4m, but according to the calculation of erosion requirements, laying of gabion should have a certain length, such as 10 ~ 15m, at this time several gabions with a lack of line Bundled bundle connection, such a gabion that assembly gabions, gabions of this kind of the following disadvantages: 1. The cost of materials, because the two gibbons longitudinal splice at the two cross-section, due to the diversion of diaphragms Doubled 2. Assembled gabion with 鉄 harness bundle, when the gabion sag is not consistent with the strength of the longitudinal reinforcement by the main frame, scouring the rear
