摘要
钢筋混凝土变形桩是一种新桩型,其桩径与扩大头直径的关系是影响桩承载力的重要因素。本文采用外罚函数法,单纯形法对变形桩直径及扩大头直径进行优化设计,得出一定荷载下桩径的取值范围和最优结果。实践表明此结果不仅具有较高的理论意义,而且具有很大的实用价值。
The variable cross-section pile is a new type of pile. The relation between the pile shaft and the expanded bodies, has a close connection with the pile support capacity. The optimization problem is solved by using an external penalty function and a simple method. The practice shows that the result has theoretical meaning and practical value to optimum design of the diameters of the pile shaft and the expanded bodies.
