解釋
樁的動載荷試驗-
In view of bearing capacity of the elastoplastic theory analysis, the author made a comparison between the achieved bearing capacity limit load pi / 4 of round base ( space problem ) and the limit load pi / 4 of bar groundwork foundation design ( plane problem ) from soil mechanics at home and abroad as well as foundation criterion, and explained why the value of formula in present design criterion from soil mechanics is inclined to be conservative. in the light of the author ' s many years experience of vibration test on the spot and the research work of relevant projects, the author worked over the dynamic pile testing of the bearing capacity of foundation and batholith, and gathered the parameter of dynamic analysis and testing. the author also talked over the difficult point of pile foundation design criteria in present batholith engineering world, i. e. the confirmation of batholith bearing capacity of pile end, from the following aspects : a ) confirmation of single axis counter - pressure strength of rock in house ; b ) f. e. m calculation of elastoplastic model ; c ) calculation of soil mechanics ; d ) deep well load test
然後，對巖土工程領域至今尚未解決，甚至不為人注意的考慮地基變形的地基承載力問題進行了實用化的探討，提出了考慮地基變形的地基承載力上程計算方法；對基於彈塑性理論分析的地基承載力國內尚未見報道的空間問題得到了圓形基礎（空間問題）的承載力界限荷載p _ （ 1 / 4 ） ，並與國內外土力學專著及地基基礎設計規范中的條形基礎（平面問題）的界限荷載p _ （ 1 / 4 ） ，進行了對比，從而定量上解釋了目前設計規范引用土力學承載力公式值偏於保守的這一情況；根據本文作者多年從事現場地基工程振動試驗及相關課題的研究工作，本文以截頭錐模型模擬地基，對地基（巖基）承載力的動測法進行了研究，為各類地基（包括巖基） ，匯總了動力分析和檢測川的參數：針對日前巖土工程界應用樁基設計規范中的難點? ?樁端巖基承載力的確定問題，從巖石室內單軸抗壓強度確定、基於彈塑性模型的有限單元法計算、土力學計算及深斤載荷試驗四方面進行了深入討論；本文作者根據多年現場載荷試驗的工程實踐，對深井荷試驗裝置的核心部分? ?反力裝置，設計了側壁支撐反力加載系統，該加載系統具有實用、簡便、穩定及安個等優點。 -

Considering that the load was added in steps, dynamic design based on in - sile test parameter is an effective and practical method. based on the author ' s experience of djm composite ground engineering, and two projects of highway djm composite ground, it systemically analyzed and summarized the in - site test result as well as the settlement deformation, pore water pressure dissipation, deep horizontal displacement, stress ratio, stress of pile. etc. it also compares the in - site test results of djm composite ground with or without rigid bearing stratum, and draws many practical conclusions
根據筆者多年粉噴樁加固路基工程的經驗，結合兩個高等級道路粉噴樁加固路基工程實例，全面系統地分析和總結了現場試驗路段試驗結果，對攪拌樁復合地基沉降特性、孔壓消散特性、深層水平位移特性、樁土應力比、樁身應變等作了深入細致地分析，對有硬持力層和無硬持力層（浮樁）的粉噴樁復合地基現場試驗結果作了對比，得到了許多有應用價值的結論。
