【摘要】：为克服圆锥动力触探和标准贯入试验中完全受重力场控制的弱点,从而提高其在非水平探测面中的适用性,提出了用设备动力代替部分重力做功的思路,从原理上分析了其合理性与等效性,并根据设备做功相等的原则提出了锤击数的修正公式。然后,着重以轻型动力触探为例,考虑到实际应用中可操作性和便捷性,对相关技术参数具体取值进行了探讨,在此基础上设计了新的多向轻型动力触探设备的详图,提出了设备操作要点。最后对多向圆锥动力触探和标准贯入设备的研究与应用前景进行了概要小结。
[Abstract]:In order to overcome the weakness that cone dynamic penetration and standard penetration test are completely controlled by gravity field, and thus improve its applicability in non-horizontal detection plane, the idea of replacing partial gravity work with equipment power is put forward. The rationality and equivalence are analyzed in principle, and the modified formula of hammer number is put forward according to the principle of equal work done by equipment. Then, taking light power penetration as an example, considering the maneuverability and convenience of practical application, the specific value of relevant technical parameters is discussed, and on this basis, the detailed drawing of new multi-direction light power penetration equipment is designed. The main points of equipment operation are put forward. Finally, the research and application prospect of multi-directional cone dynamic penetration and standard penetration equipment are summarized.
