1.1本试验方法包括在饱和粘土和粉土中进行现场十字板试验，以测定不排水抗剪强度。要评估试验的适用性和解释，需要了解进行每个十字板试验的土壤性质。本试验不适用于试验期间可能允许排水的砂土。 1.2本试验方法涉及陆上试验和钻孔试验，或通过自钻或连续推土方法从地面进行试验。 该方法不专门针对可能需要特殊测试要求或设备变化的海洋测试。用户可参考ASTM STP 1014，了解有关现场叶片剪切试验的更多信息。 1.3该方法通常与流体旋转钻井（D 5783）或空心杆螺旋钻（D 6151）结合使用。一些设备将叶片缩回防护靴中，用于推进和增量测试。取样，例如薄壁管（D 1587）通常与叶片试验相结合。 地下岩土工程勘探按照规程（D 5434）进行报告。 1.4粘性土的不排水抗剪强度和敏感性也可以在无侧限压缩D 2166和实验室十字板试验（D 4648）中测量。 1.5以国际单位制表示的数值应视为标准。括号中给出了英制单位。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This test method covers the field vane test in saturated clay and silt soils for determination of undrained shear strength. Knowledge of the nature of the soil in which each vane test is to be made is necessary for assessment of the applicability and interpretation of the test. The test is not applicable for sandy soils which may allow drainage during the test. 1.2 This test method addresses testing on land and for testing in drill holes or by self drilling or continuous push methods from the ground surface. This method does not address specifically marine testing where special test requirements or variations in equipment may be required. The user is referred to ASTM STP 1014 for additional information on in-place vane shear testing. 1.3 This method is often used in conjunction with fluid rotary drilling (D 5783) or hollow-stem augers (D 6151). Some apparatuses have the vane retracted in protective shoe for advancement and incremental testing. Sampling, such as with thin wall tubes (D 1587) is often combined with vane testing. Subsurface geotechnical explorations are reported in accordance with practice (D 5434). 1.4 Undrained shear strength and sensitivity of cohesive soils can also be measured in Unconfined Compression D 2166 and Laboratory Vane Test (D 4648). 1.5 The values stated in SI units are to be regarded as the standard. English (Imperial) units are given in parentheses. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
