is not a common static pile load test (kentledge). drilling a micopile at 4 side of the tested pile as anchor and use hign strength strand (same for post-tensioning system) as transfer agent. must very careful to the test beam design due to the high test load. always talking about 1500kN and above. |

对对。。。。 不过我们没有另外钻reaction auger....我们用回working pile 当做reaction auger 咯。。。
哪你的WORKING PILE不是要設計成TENSION PILE?
你有沒有覺得你的PILE的REBAR增加很多.....? |

working pile is a pile u want to test and use as criteria for the overall piling system design. Many soil parameter u can get from the pile load test.
. tension pile is micropile at 4 side of the tested pile. |

虽然是需要用英文解释会比较准确又容易明白，不过这里还得尊重版规，麻烦用中文发表。谢谢！

回复 9# cyruschen 的帖子
那么distance 会远吗？？
1。打 4 nos micropile 在旁边的话， distance from test pile 是多少？？？
2。你们用旁边的working pile 来拉的 , distance 不会比4 nos micropile 的method 远很多吗？？？
有 method of statement 吗？？ |

if the pile layout is permit, sure using of other working pile as reaction pile is best solution.but is not a common case in pratice. the pile distance(related to column spacing) is common 8m and above for modern high rise building.then, the plate girder (test beam ) length became a crucial. the plate girder's weight easily exceed 18 ton for 6.0m length with test load up to 2500 tonne. Just imaging how much the cost for the girder and the setting up work? |

如果你用4支working pile来当reaction anchor， 那么当你apply load（by jacking）时，tested pile被压下的同时4支reaction anchor不是会被扯上来吗？
那test完之后这4支working pile就已经＂浮＂上来了。。。当正真的load apply在这4支pile时，它们的load taking就和其他piles不一样了，对吗？
不晓的method of statement里的计算有包括这些吗？ |
