哈尔滨第三电厂(以下简称哈三厂)位于呼兰河的漫滩阶地上。由于河口三角洲长期沉积存在多变的弱软夹层,地基工程采用了桩基结构,总桩数6300根,现将主要情况简介如下: 一、设计施工根据工程地质条件和试桩数据,设计有效桩长为14米和18米两种,混凝土采用300号,桩的断面350×350毫米,主筋4根φ18, Harbin No. 3 Power Plant (hereinafter referred to as Harbin No. 3 Plant) is located on the floodplain terrace of the Hulan River. Due to the long-term sedimentation in the delta of the estuary, there is a weak and soft interlayer. The foundation project uses a pile foundation structure with a total number of 6,300 roots. The main conditions are summarized as follows: 1. Design and construction According to engineering geological conditions and test pile data, design effective piles. It is 14 meters in length and 18 meters in length. The concrete uses No. 300, the section of the pile is 350 X 350 mm, and the main ribs are 4 φ18.
