《中华人民共和国电力行业标准(DL/T5102-1999):土工离心模型试验规程(英文版)》内容简介:This Standard is compiled according to the arrangement of Notice onPrinting the Development and Revision Plan of Professional Standards(Document No. 28, 1998) issued by the former Ministry of ElectricPower.
Geotechnical centrifugal model test is a new technology. It canvisually and correctly reveal the engineering characters of the soils,provide the basis for the design and construction, and verify the servicecondition of the structures. It is also be used as a method forfundamental research. This technology has been widely applied inmany countries.Since 1980s, lots of academic institutes anduniversities in China have established their own centrifuge modelinglaboratories which have provided valuable data for design andconstruction of many key projects. In addition, important researchresults have been achieved with respect to fundamental research.
Centrifugal model test is complicated in the aspects ofequipment, measuring instrument, model preparation, data and videoacquisition, etc.. Nevertheless, it is vital to ensure the safety of testand to avoid accidents. It is necessary to develop operation procedureand requirement in order to ensure the reliability of the test data andsafety operation of equipment and instrument. So this Standard isformulated.

土壤中含有有机质物质,如树根、草根之类的可以燃烧的物质,这些东西被燃烧之后就会减掉一定的质量,这就是土的烧失。减少量占土壤总量的百分比为土的烧失量。
软土地基上土工织物加筋堤的离心模型试验研究
以黄骅港防波堤工程为依托,对有、无土工织物加筋垫层及不同织物加筋条件下堤坝和软土地基的变形与稳定进行了离心模型试验对比研究。得到了地基土体的竖向与水平位移分布规律以及孔隙水压力的消散特性。研究表明:土工织物加筋垫层的加筋机理源于其对土体的侧限效果,铺设土工织物后能有效地减小地基的沉降,并能够限制浅层土体的侧向变形;为使土工织物的加筋效果能够得以充分发挥,要求织物的强度及模量要与垫层的界面强度相匹配。

土工离心模型试验(geotechnical centrifugal model test),是利用离心机提供的离心力模拟重力,按相似准则,将原型的几何形状按比例缩小,用相同物理性状的土体制成模型,使其在离心力场中的应力状态与原型在重力场中一致,以研究工程性状的测试技术。
