摘要

摘要:研究目的:现行土工格室相关产品标准无法满足铁路工程建设需求,需要结合铁路特点编制行业标准。标准编制采用铁路工程的功能需求与产品性能指标紧密结合的思路,为确定不同产品的工程适用性,需要系 统性地开展产品性能试验研究。研究结论:(1)研究提出了直角撕裂抗力、对拉强度、悬挂负重时间、结点抗紫外线强度保持率等新的性 能指标,更为全面地反映了产品性能;(2) 土工格室不同产品的性能指标存在较大差异,通过试验测试提出了 铁路地基处理、基床加固、边坡防护等工程领域的适用产品;(3)铁路行业标准的编制统一了产品名称和性能 指标,使产品生产企业和铁路的设计、施工、监理等部门均有规可依,规范了土工格室在铁路工程上的应用。

Abstract

Abstract : Research purposes : The current product standard of geocell cannot satisfy the construction requirement of railway engineering,and it is necessary to establish the professional standard according to the characteristics of railway engineering. The functional requirements of railway engineering and performance indexes of product are closely combined in the process of standard establishment. Systematic research about product performance index should be proceeded in order to determine the engineering applicability of different products. Research conclusions:( 1 ) The new performance indexes of tear resistance, tensile strength between geocell slice, suspended loading time and uvioresistant percentage retained strength of node are put forward in the new standard,and reflect theproduct performance more comprehensively. (2) There are large differences of performance index between different geocell products according to the test results, the applicable products for foundation treatment, subgrade reinforcement and slope protection in railway engineering are proposed. ( 3 ) The establishment of railway industry standard unifies the product name and performance index, makes the production company and design, construction, supervision departments in railway engineering refer to, and specifies the application of geocell in railway engineering.
