光伏支架微型灌注桩基础采用中美规范设计对比分析

Comparative Analysis for Micro Cast-in-place Pile Foundation of PV Support Designed by Chinese and American Codes

随着世界各国对能源体系寻求绿色低碳循环发展的愈发重视和国家"一带一路"的不断推进,中国企业在海外承揽的光伏工程不断增多,其中绝大部分项目业主明确要求采用美国等国际通用规范进行投资投标报价。基于国外某光伏投标项目,分别采用中国规范和美国规范对同一光伏阵列进行了基础设计,分析两种规范对于微型灌注桩设计计算的异同,计算得到两种规范在桩基工程量上的差异。最后,提出针对此类项目的设计建议。

With the increasing attention of countries in the world to seek green and low-carbon cycle development for energy system and continuous promotion of the national "One Belt And One Road" strategy,the number of overseas photovoltaic projects contracted by Chinese enterprises is increasing,and most of the project owners explicitly require the design units to adopt international general specifications such as American codes for bidding quotation.Based on an overseas photovoltaic bidding project,the same PV array foundation is designed by Chinese code and American code respectively,and the similarities and differences between the two codes for the design and calculation of micro cast-in-place pile are analyzed,and obtain the differences of pile foundation bidding quantities between the two codes.Finally,the design suggestions for such projects are put forward,in order to provide reference for overseas photovoltaic project designers.
