The paper determines compaction degree of subgrade making use of pumped sand, cutting ring ,nuclear density instrument and drop hammer frequent mensuration methods.

采用灌砂法、环刀法、核子密度仪法、落锤频谱式快速测定仪法4种方法对检测路基压实度的测试结果进行了比较分析；并以灌砂法作为现场测定压实度的标准方法，将其他方法与灌砂法进行回归标定，得出了相关关系，进一步证实了采用灌砂法作为路基压实度检测的标准方法是值得推广的。

This paper presents two methods to estimate the relationship between dent depth and contact force, respectivelyβamend method and deflection compensate method, which are developed by using a clear geometrical relation to express indent, incursion profile and deflection difference.

本文以一种新的观点，用一个明确的几何关系来确定压痕、压头与板的接触面剖面及接触中心点与边界点之间的挠度差三者之间的关系，提出两种近似预测接触力与压痕深度关系的方法——β修正法和挠度补偿法。

Based on the principle that there exists an equal pressure drop for a tube with average parameters and another one with deviation parameters the authors have worked out an iterative procedure for determining the flow rate deviation factor η 1 of a boiler water wall.

The standard workpiece of the ring compression test by Lee and Altan will be used in this report. The specimen will first annealed to eliminate the internal stress and then through different ways of machining to produce different roughness of surface and different direction of machining marks. The ring compression test with various lubricants and dry friction were carried out at room temperature. The experiment results were drawn on the diagram of friction factor developed by Lee and Altan to compare the influence of the roughness of surface to plastic forming with or without lubricants.

实验将依Lee and Altan压环试验所用之标准压环试片进行，实验试片先经退火处理消除内应力，再将试片以各种不同之加工方式制作成具有不同的表面粗糙度，与不同刀痕方向之摩擦面，再於常温环境下实施乾摩擦与添加不同润滑剂之压环试验，将实验结果所得之数据绘制於Lee and Altan之定剪摩擦系数图中，以比较其不同表面粗糙度对塑性成形之影响，同时也说明在各种不同表面粗糙度下添加各种润滑剂对成形之影响。

When a sudden power failure or accident or normal pump stops when the pump stops, the valve inlet water velocity to reduce stress Agency, the valve plate also fall, when its velocity is zero (that is, inlet flow rate is zero Department), large valve plate because of its own gravity and rapidly turn off (time 3s ~ 5s), the majority of water to prevent backflow, when the valve before and after the formation of a water pressure, water stress, on the one hand through the small valve at the bottom of the three slot for pressure relief vent pressure. 4 water stress from the bypass tube into the cavity patch up the control room (this process for the suction pressure chamber that can effectively absorb the energy of water), when water stress on cavity than inferior vena cava, the pressure of water promote the diaphragm down mobile , the current cavity pressure of water being squeezed out all the small valve plate slowly drop back to standby status, the process time to ease closure adjustable (3s ~ 150s), then the valve has been fully closed, watertight.

当突然停电或事故停泵或正常停泵时，阀门进水口处压力水流速降低，大阀板也随之下降，当其流速为零时，大阀板由于自身重力而迅速关闭（时间3s～5s），可防止大部分水倒流，此时阀门前后形成一种水压差，压力水一方面通过小阀板底部的三条泄压槽进行泄压。4）压力水从旁通管进入膜片控制室上腔（此过程为吸压腔，能有效吸收一部分水能量），当上腔压力水大于下腔时，压力水推动膜片往下移动，当下腔压力水全部被挤出来时，小阀板缓缓下降，恢复到待机状态，此过程中缓闭时间可调节（3s～150s），届时阀板已全部关闭，滴水不漏。

Equalizers are spacer blocks mounted on either the blank holder surface or the die face that maintain a specific gap between the die face and blank holder surface.

平衡块是一些安装在压边圈或凹模型面上用来维持压边圈和凹模间的压边面间隙的垫片。

Second, considering the influence of well resistance, smear effect and structure breakage of thick soft clay, the equivalent calculation method is proposed. That is, the partially penetrating sand drain ground is viewed as the double-layered ground, and its consolidation is analyzed with 1-D consolidation theory, through the transformation from 3-D consolidation to 1-D consolidation in the region of sand drain. This can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under-lying soft layer. To the double-layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory.

然后，在充分考虑竖井区井阻、涂抹作用以及土体结构损伤破坏对固结影响的基础上，将未打穿竖井地基合理地转化为双层地基，按一维固结理论计算，克服了传统固结计算方法在竖井处理区与下卧层交界面处存在孔压间断的缺点；在此基础上，从超载预压法的基本原理出发，分析了双层地基超载预压固结、沉降机理，推导了多级等速加、卸载情况下双层地基的固结计算公式，进一步完善了双层地基固结理论。
