摘要
目前还没有足够的信息来充分了解DPSH (Dynamic Probe Super Heavy)探测中的杆摩擦机制。因此,提出了一种方法来区分轮廓,其中摩擦导致过多的打击计数基于归一化轮廓。虽然受摩擦影响的DPSH剖面很难解释,但未受摩擦影响的DPSH剖面与SPT(标准侵透测试)剖面表现出更好的等效性,特别是用于筛选合格的(SPT冲击计数为100 - 30)地面条件。
Establishing competent ground conditions with the DPSH
Insufficient information is currently available to fully understand the mechanism of rod friction in DPSH (Dynamic Probe Super Heavy) probing. Consequently, a method is proposed to distinguish profiles in which friction results in excessive blow counts based on normalised profiles. While friction-impacted DPSH profiles are difficult to interpret, those unaffected by friction show better equivalence to SPT (Standard Penetration Test) profiles, especially if used to screen for competent (SPT blow counts > 30) ground conditions.
期刊介绍:
The Journal of the South African Institution of Civil Engineering publishes peer reviewed papers on all aspects of Civil Engineering relevant to Africa. It is an open access, ISI accredited journal, providing authoritative information not only on current developments, but also – through its back issues – giving access to data on established practices and the construction of existing infrastructure. It is published quarterly and is controlled by a Journal Editorial Panel.
The forerunner of the South African Institution of Civil Engineering was established in 1903 as a learned society aiming to develop technology and to share knowledge for the development of the day. The minutes of the proceedings of the then Cape Society of Civil Engineers mainly contained technical papers presented at the Society''s meetings. Since then, and throughout its long history, during which time it has undergone several name changes, the organisation has continued to publish technical papers in its monthly publication (magazine), until 1993 when it created a separate journal for the publication of technical papers.
