通过室内小比尺的模型试验,可以进一步为确定DX桩沉降计算公式提供必要的依据。在小型模型试验箱中,通过采用杠杆加砝码的装置对22 mm桩径的DX桩在砂土中进行研究,测定单桩的桩顶荷载-桩顶位移曲线,确定承载力,并与相同情况下的直孔桩进行对比;同时,利用微型土压力盒测定土中应力变化,研究荷载在土中的传递规律。试验结果表明,DX桩的承载力及沉降特性明显优于直孔桩;承力盘在上部和下部时,DX桩尽管承载力相差不大,但是盘在下部时会增大桩端附近土体的应力;两个承力盘的DX桩,两盘受力比较一致,且盘受力的影响范围,在竖

长期以来隧道衬砌水压力问题,一直是人们争论的焦点。依托宜万铁路岩溶隧道工程,对不同防排水方式(即全封堵、堵排结合及排放方式)的隧道衬砌水压力分布规律进行研究,研究方法主要采用模型试验及现场测试方法,模型试验的比例尺为1∶16,试验台架可同时施加土压和水压。通过模型试验得出水压力分布规律:全封堵条件下衬砌背后水压力不能折减,注浆圈也不能有效减小水压力;隧道内排水后衬砌背后水压力明显减小,并随着排水量的增加,水压力基本成直线下降;相同排水量时,注浆效果越好,衬砌背后水压力减小越明显;隧道采用全排导方式时,衬砌仍承受一定的水压。由模型试验得出的水压分布规律的部分结论,在现场水压力测试中得到了验证。

Blood pressure monitoring has come a long way from the initial observations made by Reverend Hales in the 18th century. There are none that deny the importance of monitoring perioperative blood pressure; however, the limited ability of the current prevalent technology (oscillometric blood pressure monitoring) to offer continuous blood pressure measurements leaves room for improvement. Invasive monitoring is able to detect beat-to-beat blood pressure measurement, but the risks inherent to the procedure make it unsuitable for routine use except when this risk is outweighed by the benefits. This review focuses on the discoveries which have led up to the current blood pressure monitoring technologies, and especially the creation of those offering non-invasive but continuous blood pressure monitoring capabilities, including their methods of measurement and limitations.
