在风电塔架基础设计中,常见的正八边形扩展基础基底压力计算还没有成熟的公式和相应的计算表格,这给设计者带来非常不便,即使进行等效计算,也会产生一定的误差。通过对风电八边形扩展基础的受力进行分析,推导得到风电扩展基础的基底压力计算方法,并根据设计人员习惯查表的特点,给出了八边形基底压力的计算表格,大大方便了使用。依托某个工程进行基底压力计算,验证了该方法的方便性和可靠性。
In the wind turbine tower foundation design, there is no mature formula and corresponding calculation form for the calculation of the base pressure of the common positive octagonal expansion foundation. This brings great inconvenience to the designer, even if equivalent calculations are performed, it will also produce certain errors. . Through the analysis of the stress of the octagonal expansion foundation of wind power, the base pressure calculation method for the base of wind power expansion is deduced, and according to the characteristics of the habits of the designers used for checking the table, the calculation form of the octagonal base pressure is given, which is greatly convenient. use. Relying on a project to calculate the base pressure, the convenience and reliability of the method are verified.
