土工布在工程建设中的作用Effect of Geotextiles in engineering construction
土工布在工程建设中的作用
土工布是由合成纤维通过针刺或编织而成的透水性土工合成材料，又分为有纺土工布和无纺土工布，它具有优良的过滤、排水、隔离、加筋、防渗、防护作用，具有重量轻、抗拉强度高、渗透性好、耐高温、抗冷冻、耐老化、耐腐蚀的特性。
土工布它作为一种新型的土工材料，在各大领域的工程建设中起着非常重要的作用，详细内容介绍如下：
1、公路路面的养护保湿作用：长丝土工布能够起到保持混凝土内部温度和湿度相对恒定，能有效提高混凝土早强，减少微裂缝的产生作用。
2、过滤作用的应用 长丝土工布能让水份通过，又能有效地阻止土壤颗粒通过，从而防止土粒的流失而造成土体的破坏
3、铁路路基的加筋作用：利用长丝土工布增强软土地基承载力、提高土体的抗拉强度和抗变形能力，增加土体和土工布之间的磨擦阻力，防止地基的沉降，继而达到整体稳定性的作用。
4、水工建筑的隔离作用：利用长丝土工布对具有不同物理性质的建筑材料进行隔离。使两种或多种材料间不流失，不混杂，保持材料的整体结构和功能，使构筑物载承能力加强。
5、防渗作用的应用 复合土工膜和复合型土工材料，可以防止液体的渗漏，气体的挥发，保护环境或建筑物的**。
6、排水作用的应用 无纺土工布可以在土体中形成排水通道，把土中水份汇集起来，沿着材料的平面排出体外.
Effect of Geotextiles in engineering construction土工布在工程建设中的作用
The geotextile is permeable geosynthetic by synthetic fiber byacupuncture or woven, divided into a nonwoven geotextiles andgeotextile, it has a filter, drainage, isolation, reinforcement, the anti-seepage, the protective effect of good, has the characteristics of light weight, high tensile strength, permeability sex is good, high temperature resistant, anti freeze, aging resistance, corrosion resistance.
Filament geotextile it as a new type of geosynthetics, plays a very important role in various fields of engineering construction, the detailedcontents is introduced as follows:
1, the highway pavement maintenance moisturizing effect: filament geotextile is able to maintain a relatively constant temperature andhumidity inside the concrete, can effectively improve the early strength of concrete, reduce the effect of micro cracks.土工布在工程建设中的作用
2, the filtration function of the application of filament geotextile can letwater through, but also can effectively prevent the soil particles pass through, thereby preventing soil particle loss caused by the failure of soil mass
3, the railway roadbed reinforcement effect: using filament geotextilereinforced soil to improve the tensile strength and anti deformation capacity, bearing capacity of soft soil foundation, increases the friction resistance between soil and geotextile, prevent the settlement of the foundation, and then achieve the overall stability of the role.
4, the role of isolation of hydraulic engineering: isolation of having different physical properties of building materials by using filament geotextile. The loss of two or more materials, not mixed, maintain the overall structure and functional materials, the load bearing capacity ofstrengthened structures.土工布在工程建设中的作用
Application of composite geomembrane, seepage control effect of 5 and composite geotextile materials, can prevent the liquid leakage, the volatile gas, Protect environment or the safety of the building.
Application of 6, drainage of the non-woven geotextile can form a drainage channel in the soil, the soil moisture together, along the materialplane from in vitro.
