Research and application of the dynamic consolidation method for foundation bed treatment 强夯法地基加固机理分析与应用
Combining the project practice , it is very necessary to deeply study two consolidation methods . in this thesis , first of all , the technical characteristic and consolidation principle of dynamic consolidation method and dmm are discussed 强夯法和深层搅拌法的加固机理不同,施工工艺也截然不同,深入研究两种加固方法的特点,并结合工程情况选择实施可以大大提供工程建设的功效。
Abstract : the mechanism of the combining work of gravel piles and dynamic consolidation method used in improving soft soil foundations is mainly discussed . based on an example introducing the application of the new method , some problems exiting in the practice are debated 文摘:就碎石桩法与强夯法结合处理软土地基工艺的机理作一探讨,并结合工程实例, ,就实际存在的几点问题进行了讨论。
This includes the consolidation principle , the scope of application , design method , construction technique , quality control and so on . secondly , how to select and estimate a scheme of foundation consolidation are also discussed . the technique characteristic of dynamic consolidation method and deep mixing method are analyzed in the paper 本文首先对强夯法和深层搅拌法的技术特点和加固机理进行论述,充分阐述两种加固方法的加固机理、使用范围、设计方法、施工工艺和质量控制等;接着论述地基加固方案的选择和评价方法,并分析强夯法和深层搅拌加固技术的技术特点,为工程选用合适的地基加固方案奠定基础。
There are many methods of foundation consolidation for civil engineering , such as soil exchange method , prepress method , dynamic consolidation method , vibrancy rushing method , soil and podsol dense pile method , sand pile , cement - coal - powder and gravel pile method , deep mixing method , high - pressure eject masonry , etc . the dynamic consolidation and deep mixing method ( dmm ) are very common in project construction 目前国内外地基处理的方法很多,主要的地基处理方法包括:换填法、预压法、强夯法、振冲法、土和灰土挤密桩法、砂桩法、水泥粉煤灰碎石桩法、深层搅拌法以及高压喷射注浆法等。其中强夯法和深层搅拌法是工程建设中较常用的加固方法。
The primary purpose of this paper is that gives a particular explanation of the work principle and construction technique for the dynamic consolidation method and ddm . it also provides the evaluating schemes for foundation consolidation . so we can get some useful methods for foundation consolidation in civil engineering 文章的最终研究目标是详细说明强夯法和深层搅拌桩加固技术的工作机理及施工工艺方法,并提出相应的地基加固评价选用方法,从而为工程建设中进行地基处理提供方法和依据。
Dmm , which is another form of foundation consolidation , can increase the carrying capacity of soft soil and decrease the settlement and enhance the slope stabilization effect . the consolidation principle and construction techniques of dynamic consolidation method and dmm are quite different from each other 水泥土深层搅拌法( dmm , deepmixingmethod )是用于加固地基的另一种形式,利用深层搅拌法可以达到增加软土地基的承载能力,减少沉降量,提高边坡稳定性的功效。
This paper introduces the current study situation and affecting factors of the dynamic consolidation method , then this paper is about the application of the technology for the strong tamping in reinforcing and treating the groundsill , it introduces by analyzing the principles of the strong tamping and the example in application . . combining several the actual practices of adopting the power tamp method treatment of wet and sunk loess foundation , effect using strive ramming method process has been analyzed in this paper 本文阐述了强夯法的研究现状和影响因素,然后通过对强夯机理的分析,探讨了强夯工艺在地基加固处理中的应用;结合几个工程实例中采用强夯法处理湿陷性黄土地基的具体实践,分析了用强夯法处理湿陷性黄土地基的效果,较详细地介绍了该方法的设计要点、施工工艺、检测项目、控制标准等。
