土钉墙在工程应用中的问题及改进方法的探讨

土钉墙凭借一些显著的优越性被广泛应用于基坑工程的开挖支护，并带来了巨大的社会和经济效益。然而，国内存在大量盲目使用土钉墙的现象，由于没有认清适用范围，加上设计和施工中存在大量的问题，导致基坑安全事故屡见不鲜。因此需要全面认识土钉墙的作用机理，了解土钉墙的优缺点、重视其施工水平。针对土钉墙在岩土工程应用中存在的问题做了详细讨论，并提出了改进方法和土钉墙今后研究的方向，对土钉墙的耐久性、抗震、蠕变以及无损检测、变形的预测、复合土钉墙等方面展开研究将具有非常深远的意义和良好的发展前景。

Limitations of Soil Nail Wall in Engineering Application and the Improvement Method

Soil nail wall is widely used in supporting foundation pit excavation and brings great social and economic benefits.However,soil nail wall is blindly used in China at present.People are not aware of its limitations and applicable scope,giving rise to problems in the designing and construction which lead to lots of accidents.In view of this,we should have a comprehensive understanding of the action mechanism of soil nail wall.At the same time,we need to understand its superiorities and limitations and pay attention to its construction.This paper lays emphasize on problems in the use of soil nail wall,and gives advices to make it better.What’s more,we discuss the future use of soil nail wall,for example,the durability of soil nail wall,anti-seismic resistance,creep deformation,nondestructive examination,deformation estimation,composite soil nail wall and so on.Research on these aspects will be of far-reaching and promising importance.
