Extracting method for test engineering piles

The invention provides an extracting method for test engineering piles, comprising the following steps of confirming codes and value ranges of pile numbers, and initializing a pile number array according to the codes and the value ranges; appointing the pile numbers respectively belonging to a baring platform group and a bearing force group from the pile number array; setting an engineering pile extracting condition according to basic information of engineering piles and a selected engineering pile testing method so as to confirm the extracting proportion and amount of the pile numbers belonging to the bearing platform group and the bearing force group; randomly extracting the pile numbers according to the extracting proportion and amount of the pile numbers; and correspondingly confirming the test engineering piles according to the pile numbers obtained through random extraction. The extracting condition of the engineering piles is met. 本发明提供了种试验用工程桩的抽取方法，包括以下步骤：确定桩编号的编码和数值范围，根据编码和数值范围初始化出个桩编号阵列；在桩编号阵列中指定分别属
