双向土工格栅包括双向双向土工格栅以及各种类型的双向土工格栅,其属于一种合成性的材料,在目前的土木工程中,其应用较为广泛。其内部的分子结构可以进行高度拉伸,其具有较强的延展性和弹性,其所具有的弹性以及延展性与低碳钢水平相比较为相似,其应用到土木工程中,可以有效的提升土木工程的施工质量,使得其具有较强的稳定性,同时也能够有效的提升工程的牢固度,使得土木工程可以得到良好的建设但是,在施工条件较为恶劣的防洪大坝中,应用双向土工格栅还属于较新的--种尝试，因此,针对双向土工格栅在防洪大坝施;工中的应用效果进行研究具有一定的实际意义和参考价值。
Two way geogrid includes two-way geogrid and all kinds of two-way geogrid. It is a kind of synthetic material and widely used in civil engineering. Its internal molecular structure can be highly stretched, and it has strong ductility and elasticity. Its elasticity and ductility are similar to the level of low carbon steel. When it is applied to civil engineering, it can effectively improve the construction quality of civil engineering, make it have strong stability, and also effectively improve the firmness of the project, So that civil engineering can get a good construction, but in the construction condition of the flood control dam is relatively bad, the application of two-way geogrid is still a relatively new attempt, therefore, the research on the application effect of two-way geogrid in flood control dam construction has a certain practical significance and reference value.
       就防洪大坝来说,其在施工的过程中应用双向土工格栅应该符合以下几点要求针对每一标段的堰墉中的杂草都要进行有效的清除，同时也要对堰墉上部出现腐烂的面层进行有效的清洗,在将这些污垢都消除之后,再对堰墉内部的积水进行排出处理，直到淤泥出现后,可停止积水的排出,在淤泥表面上进行土层的铺盖,在土层铺盖完成之后,就需要依据施工质量的具体要求,来进行双向土工格栅的安置施工。在将双向土工格栅应用到堤基之中后,就需要依据施工的具体要求，对堤基进行合理的设计,从而保障其可以满足防洪大坝堤基施工的需求,在大堤完成施工之后,大堤通常会因为各种因素的影响,而出现沉降变形现象,一般沉降变形的幅度都会在40cm范围内，但是这样的沉降变形不会影响到防渗施工,因此,可以忽略不计。
For the flood control dam, the application of two-way geogrid in the construction process should meet the following requirements: for each section of the weir, the weeds should be effectively removed, and the rotten surface layer on the upper part of the weir should be effectively cleaned. After these dirt are removed, the accumulated water inside the weir should be discharged until the sludge appears, The drainage of accumulated water can be stopped and the soil layer can be paved on the silt surface. After the soil layer is paved, the two-way geogrid shall be placed according to the specific requirements of construction quality. After applying the two-way geogrid to the embankment foundation, it is necessary to design the embankment foundation reasonably according to the specific requirements of the construction, so as to ensure that it can meet the needs of the construction of the dam foundation for flood control. After the completion of the construction of the embankment, the settlement and deformation of the embankment usually occur due to the influence of various factors, Generally, the magnitude of settlement deformation will be within 40 cm, but such settlement deformation will not affect the anti-seepage construction, so it can be ignored.
       施工准备_依据防洪大坝工程的实际应用和设计的要求,选择标段中的6处的堰塘来进行施工研究分析_在施工开始之前, 需
Construction preparation: according to the actual application and design requirements of flood control dam project, 6 weirs and ponds in the bid section are selected for construction research and analysis. Before the construction, it is necessary to
       要做好相应的施工准备工作,准备好施工中需要应用到各个材料，如双向土工格栅以及塑料扎带等。另外，也需要依据施工的具体需求,选择合适的施工技术和措施,对施工的设备和器具进行有效的质量保障,在应用于施工之前,要对各种器具的性能以及设备的性能进行反复的检验,从而保障其在实际的应用中,能够充分的发挥其应有的作用。同时, 在开展施工之前也要做好相应的质量保障措施,贯彻落实施工质量保证措施,并且邀请施工人员技术人员以及防洪大坝工程施工相关的人员一起进行技术的探讨和交流,从而使得各方明确了解施工的开展状况,也使得施工人员可以明确的了解施工图纸中的施工规范和要求,从而使得该工程的施工质量可以得到保障，进而提升堤基处理的效果。
The corresponding construction preparation work shall be done well, which shall be applied to various materials during the construction, such as two-way geogrid and plastic tie. In addition, it is also necessary to select appropriate construction technology and measures according to the specific needs of construction to effectively guarantee the quality of construction equipment and appliances. Before application in construction, the performance of various appliances and the performance of equipment should be repeatedly inspected, so as to ensure that they can fully play their due role in the actual application. At the same time, corresponding quality assurance measures shall be taken before construction, and construction quality assurance measures shall be implemented. Technical personnel of construction personnel and relevant personnel of flood control dam construction shall be invited to discuss and exchange technology together, so that all parties can clearly understand the construction status, It also enables the construction personnel to clearly understand the construction specifications and requirements in the construction drawings, so that the construction quality of the project can be guaranteed, and then improve the effect of dike foundation treatment.
       相信大家看完以上内容以后，应该也对双向土工格栅在防洪大坝施工中的运用效果有所了解了，希望会对大家有所帮助吧。
