{温度}对土工材料影响 The influence of temperature on geotechnical materials

随着土工合成材料的推广和普及，各种新的土工合成材料应用后出现了一些特殊问题，尤其是在北方寒冷地区更为严重。以下几点大家可以才考一下：

With the promotion and popularization of geosynthetics, various new geosynthetics have encountered some special problems, especially in the cold regions of the north. Here are some things that everyone can take a look at:

一、低温条件下土工材料的安全隐患

1、 Safety hazards of geotechnical materials under low temperature conditions

1、首先就是复合膜的蠕变受温度变更的影响十分大，温度越低的话，复合膜的蠕变值也会变低。

1. Firstly, the creep of composite membranes is greatly affected by temperature changes. The lower the temperature, the lower the creep value of the composite membrane.

2、冬天的冻融轮回会对复合膜的蠕变机能造成很大的影响，因为在常温的环境下，蠕变时比较牢固的，温度对其会造成十分大的影响，影响后期的利用后果以及利用寿命。

2. The freeze-thaw cycle in winter will have a significant impact on the creep function of composite membranes, as creep is relatively firm at room temperature, and temperature can have a significant impact on it, affecting the later utilization consequences and service life.

3、咱们依据低温蠕变的法则可能对其进行盘算，争夺在水平上减少对复合膜的影响。

3. We may calculate it based on the law of low-temperature creep, in order to reduce the impact on the composite membrane horizontally.

因为复合膜可能应用到各行各业当中，所以随着该产品须要量的增大，在市场上对该膜的利用量也越来越高，销售跟生产的厂家也在一直的增多，人们在进行该土工膜的选购的时候，一定要对其工作原理，这样就能抉择到后果更好的产品，更好地为企业与事业单位的施工供给有效地帮助。

Because composite membranes may be applied in various industries, as the demand for the product increases, the utilization of the membrane in the market is also increasing, and the number of sales and production manufacturers is also increasing. When purchasing the geomembrane, people must understand its working principle, so that they can choose products with better results and provide effective assistance for the construction of enterprises and institutions.

因为是利用高分子短纤维华轩资料制造而成的，所以复合膜存在比较高的抗拉强度，而且在施工当中拉紧因为延长性，也不轻易造成产品的破坏，加上与塑料进行结合生产，所以可能的维护基层不会受到介质的沾染，过载避免水消散的景象，所以越来越多的企业采取这种方法进行防浸透。其次，因为产品的抗腐化性比较强，复合膜基本上不受化学物质的影响，所以应用的后果也是相称良好的，不会受到酸碱盐的侵蚀。

Because it is manufactured using polymer short fiber Huaxuan materials, the composite film has relatively high tensile strength, and it is not easy to cause product damage due to its elongation during construction. In addition, it is combined with plastic production, so it may maintain the base layer from being contaminated by the medium and avoid the phenomenon of water dissipation due to overload. Therefore, more and more enterprises are adopting this method to prevent immersion. Secondly, due to the strong corrosion resistance of the product, the composite membrane is basically not affected by chemicals, so the consequences of application are also proportional and good, and will not be corroded by acids, alkalis, and salts.

近年来，土工合成材料在土木工程，尤其是在防洪抢险工程中的大量利用其功能，引起了宽大工程技巧人员的高地器重。对复合膜合成资料的技巧利用，国度从防渗、反滤、排水、加筋、防护等方面，提出了标准性的技巧请求，大大加快了新资料的推广利用的步调。该资料在灌区渠道防渗工程中得到普遍利用，结合施工实际，浅谈复合膜的利用技巧。

In recent years, the extensive use of geosynthetics in civil engineering, especially in flood control and emergency engineering, has attracted high attention from skilled engineers. The country has put forward standardized technical requirements for the utilization of composite membrane synthesis materials from aspects such as anti-seepage, filtration, drainage, reinforcement, and protection, greatly accelerating the pace of promoting and utilizing new materials. This information has been widely used in canal anti-seepage engineering in irrigation areas. Based on construction practice, this article discusses the utilization techniques of composite membranes.
