近年来,苏联在海港工程中已普遍采用钢筋混凝土管柱基础。最常用的两种管柱是:1)管外径为1600毫米(壁厚120～150毫米),纵筋是预应力的;2)外径为1200毫米(壁厚100～120毫米),纵筋是未加预应力的两种管柱都按每节8米或4米长预制,沉桩时在现场拼接到所需长度。 1970～1972年,苏联列宁格勒海运设计院所属水下检查组在波罗的海、黑海和日本海的一些港口进行了桩基检查。结果表明:
In recent years, the Soviet Union in the harbor project has been widely used reinforced concrete column foundation. The two most commonly used columns are: 1) the outer diameter of the tube is 1600 mm (wall thickness 120-150 mm) and the longitudinal reinforcement is prestressed; 2) the outer diameter is 1200 mm (wall thickness 100-120 mm) The tendons are prestressed without prestressing both columns are prefabricated at 8 or 4 meters long and spliced to the required length at the site during pile driving. From 1970 to 1972, the underwater inspection team owned by the Leningrad Shipbuilding Institute of the Soviet Union carried out pile foundation inspection in some ports of Baltic Sea, Black Sea and Sea of Japan. The results show:
