附录D 桩的静载试验指南轴向压缩荷载试验可以通过下述两种方法实现: (a)持续荷载试验(ML试验) (b)等速贯入试验(CRP试验) 对不熟悉的地基条件,至少需要对现场主要的各组桩预先各检测一根桩,或在大型工地至少对每100根合同桩预先检测一根桩。在决定需要检测的合同桩数时,需要考虑: (a)地方法定权威的要求; (b)地基勘察的范围和可靠度以及实际遇到的地基条件的变化; (c)对邻近工地类似环境下类似桩的现状的了解程度; (d)现场操作和监理标准; (e)布设合同桩时碰到的异常困难或重要变化;
Appendix D Guidelines for static loading tests of piles Axial compressive load tests can be performed by the following two methods: (a) Continuous load test (ML test) (b) Constant velocity penetration test (CRP test) For unfamiliar ground conditions At least one pile must be pre-tested for each of the main piles in the site, or at least for every 100 contract piles on a large site. When deciding the number of contracted piles to be examined, it is necessary to consider: (a) the requirements of the local statutory authority; (b) the scope and reliability of the foundation survey and the changes in the foundation conditions actually encountered; (c) a similar environment for the adjacent construction site (d) on-site operation and supervision standards; (e) unusual difficulties or important changes encountered in the placement of contracted piles;
