摘要： A device for determining the shear strength of rock and soil is disclosed. The device includes means for supporting the device within a borehole, a primary shaft, a plurality of shearing units slidably attached to the shaft having shear heads which are movable from a retracted position to a material-engaging expanded position, and a slip joint between adjacent shearing units such that the units operate independently from one another. The shearing units apply progressively greater normal forces on the material to be tested and sequentially shear the material being tested.In operation, the device is lowered into a borehole. Then the shearing units are moved from their retracted position to their expanded material-engaging position so as to apply progressively greater normal forces on the material to be tested. An axial force is then applied to the shaft so that the material engaged by the shearing unit closest to the anchor shears. After the material shears, the respective heads of the shearing unit are retracted and the axial force is transferred to the next adjacent shearing unit by means of the slip joint. After the material engaged by each of the shearing units is successively sheared, the shearing characteristics of the material may be determined from the known applied normal and shear forces.
摘要翻译： 公开了一种用于确定岩土剪力的装置。 该装置包括用于在钻孔内支撑装置的装置，主轴，可滑动地附接到轴上的多个剪切单元，其具有可从缩回位置移动到材料接合扩展位置的剪切头，以及在相邻 剪切单元，使得单元彼此独立地操作。 剪切单元对待测材料施加逐渐增大的法向力，并依次剪切被测材料。 在操作中，该装置被下降到钻孔中。 然后剪切单元从其缩回位置移动到其膨胀的材料接合位置，以便对待测试的材料上施加逐渐更大的法向力。 然后将轴向力施加到轴，使得由剪切单元接合的材料最接近锚剪。 在材料剪切之后，剪切单元的各个头部缩回，并且轴向力通过滑动接头传递到下一个相邻的剪切单元。 在由每个剪切单元接合的材料被连续地剪切后，材料的剪切特性可以从已知的施加的正常剪切力和剪切力确定。

摘要： A punching-shearing method for inspecting the quality of a butt welded joint comprises pressure butt welding steel members under heat to form an annular bulge around the joint portion of the steel members, punching-shearing the bulge under red heat immediately after the pressure butt welding process from one side of the bulge in parallel with the axes of the steel members by use of a shearing die having higher and lower shearing edge portions so that the higher shearing edge portions penetrate the bulge prior to the lower shearing edge portions, so as to cause the base of the bulge to remain around the joint portion in a slightly higher position than the peripheral surfaces of the steel members, and determining the quality of the joint portion from the peripheral surface of the base of the bulge remaining on the joint portion.

摘要： A vane modulus soil tester includes a multi-blade vane having a plurality of radially extended and circumferentially spaced-apart blades. The blades have cavities in which resistance-type strain gauges are carried for measuring stress on the face of the vane blades. At least strain gauges are situated so as to be "facing" each other.A further embodiment may be provided with a series of independent levels of blades of different thicknesses whereby test values may be extrapolated to zero blade thickness conditions or the insitu value. A support base is provided for securely positioning a vane rod extended axially from the vane and for applying torque to the vane through the vane rod.

摘要： A model test device for simulating environmental load and scouring effect on a suction caisson includes a laminar shear box. Multiple scouring pit simulation mechanisms are arranged around the suction caisson inside the laminar shear box, each scouring pit simulation mechanism includes a bracket disposed in the laminar shear box, the bracket is equipped with a telescopic arm connected to a cutting plate, and the cutting plate is curved fan-shaped. When the cutting plates move to positions where they are in contact with an outer wall of the suction caisson, the cutting plates are mutually connected to form a ring surrounding the suction caisson. An inner edge of the ring forms a complete circle attached to the outer wall of the suction caisson, an outer edge of the ring is higher than its inner edge, and the outer edge is located above the saturated soft clay in the water body.

摘要： An object of the present invention is to provide a gypsum-based load-bearing board for wood structural load-bearing walls which is capable of increasing the co-efficient of effective wall length without additionally using reinforcement materials or stiffening materials, and without increasing the specific gravity and/or the thickness of the gypsum-based board. The gypsum-based load-bearing board (10) for wood structural load-bearing walls includes a main member or a core member formed from a board-shaped hardened gypsum containing an inorganic fiber and an organic-based strength enhancer that exert a lateral nail resistance of 500 N or more, and a paper covering at least front and back sides of the main member or the core member to constitute the load-bearing board. The load-bearing board has a surface density of 6.5 kg/m2 to 8.9 kg/m2, exhibits an ultimate displacement (δu2) of the load-bearing wall measured by an in-plane shear test of greater than 20×103 rad (δu2), and exerts an ultimate strength (correction value) (Pu′) of greater than 7.6 kN. According to the wooden structural load-bearing walls using the load-bearing board can obtain short-term reference shear strength (P0) greater than the wooden structural load-bearing walls using similar load-bearing board having a surface density of greater than 9.0 kg/m2.

摘要： A loading frame for fiber reinforced polymer (FRP)-concrete bond tests includes a standing guide tower, a base section, and a loading beam. The standing guide tower is perpendicularly mounted to the base section. A testing load is applied to the loading beam when performing a series of FRP-concrete bond tests. A sliding end of the loading beam is positioned into a channel within the standing guide tower allowing the loading beam to be positioned at a preferred height. The engagement between the loading beam and the standing guide tower reduces secondary forces. The loading frame is mobile and may also be used with existing testing devices and systems used to perform the series of FRP-concrete bond tests.
