秦皇岛港煤码头三期工程中的翻车机房和地下廊道采用地下连续墙结构型式。翻车机房连续墙内侧直径为49.95米,璧厚90厘米,挖深17.50米。廊遭连续墙壁厚80厘米,内侧净距离11.90米,最大挖深16.50米。因此有机会对地下连续墙的计算方法问题进行较为深入的探讨,现介绍如下: 地下连续墙技术起源于欧洲,特别是对砂砾层和石灰岩构成的地基,因打桩或打板桩都比较困难,或者在市区,由于周围建筑物接近无法施工而出现了地下连续墙的结构。由于地
The dumping machine room and underground gallery in the third phase of the Qinhuangdao Port Coal Terminal use underground continuous wall structure. The inside diameter of the continuous wall of the roll-off machine room is 49.95 meters. It is 90 centimeters thick and 17.50 meters deep. The corridor was 80 cm thick with a continuous wall of 11.90 meters inside and a maximum depth of 16.50 meters. Therefore, there are opportunities for further discussion on the calculation method for underground diaphragm walls. The following is a brief introduction. The technology of underground diaphragm walls originated in Europe, especially for foundations composed of gravel and limestone, and it is difficult to piling or hitting sheet piles. Or in urban areas, the structure of the underground continuous wall has emerged because the surrounding buildings are close to being impossible to construct. Due to
