可拆卸锚索的现场试验研究

摘要：随着国家基础工程建设的发展，预应力锚索在岩土工程中的应用越来越多，预应力锚索支护技术已经成为了土木工程中一项重要的加固措施。尤其是在岩土工程中，预应力锚索常常作为临时性支护措施进行岩土体的加固处理。但是，作为临时性岩土支护措施的锚索，在工程完工后，大量地存在岩土中，不仅能够污染土壤或地下水，也会造成极大的资源浪费。因此，开发可拆卸的预应力锚索具有非常重要的工程意义。本文所提出的可拆卸锚索，拆卸原理科学，结构合理，工艺简单，通过室内与工程现场的试验，验证了开发的可拆卸锚索的工程适用性。

ln-situ experimental study on demountable anchor cable

Following the development of the national infrastructure construction,the pre-stressed anchor cable is more and more used in geotechnical engineering project and the supporting technology with pre-stressed anchor cable has become an important reinforcement measure in civil engineering project.Especially in the geotechnical engineering project,the pre-stressed anchor cable is often used as a temporary supporting measure for strengthening and treatment of rock-soil mass.However,a lot of the pre-stressed anchor cables for the temporary supporting measure will remain inside of the rock-soil mass,which can not only pollute the soil or the underground water therein,but can also cause a great waste of resources.Therefore,the development of the demountable pre-stressed anchor cable has an important engineering significance.The demountable anchor cable mentioned herein has the merits of scientific demounting principle,reasonable structure,simple process,etc.,of which the engineering applicability is demonstrated through both the indoor and in-situ experiments concerned.
