引言瑞典广泛使用预制连接混凝土桩,这是由于土壤状况和这类桩有较高的承载能力。当桩长超过13～14米时,就把它们连接起来。曾打入过长达100米的长桩。瑞典使用过三种类型的接头,即ABB、赫克斯(Hercules)及JF 接头。前两种是在二十年前产生的。桩接头的设计、制造和试验是在瑞典自然规划与建筑局颁布的指示和规定下进行的。接头强度应该相当于桩本身的强度。对受挠曲桩的分析表明,如果桩周围土壤由软粘土组成,则连接处角度变化对承载
INTRODUCTION The widespread use of prefabricated concrete piles in Sweden is due to the soil conditions and the high carrying capacity of such piles. When the pile length of more than 13 to 14 meters, put them together. Have long into the long pile up to 100 meters. There are three types of connectors used in Sweden, namely ABB, Hercules and JF connectors. The first two were produced twenty years ago. The design, manufacture and testing of pile joints are carried out under the instructions and regulations promulgated by the Swedish Ministry of Natural Planning and Construction. Joint strength should be equivalent to the strength of the pile itself. Analysis of the flexed pile shows that if the soil around the pile consists of soft clay, the angle of the joint changes to the bearing
