摘要
由于强夯作用机理复杂以及加固土体存在许多不确定的因素,以往对强夯法的研究
和设计主要依靠工程类比和经验规律。因此对强夯法进行正确、合理的研究是很有必要
的。本文以阜朝高速公路湿陷性黄土路基的处理为素材,分析了强夯法的作用机理和加
固效果的影响因素,在此基础上,通过试验对强夯法处理湿陷性黄土路基进行系统的研
究。
本文主要研究内容包括强夯法加固路基的理论研究、强夯法加固路基的试验研究
和强夯法加固路基的综合评价。其中,理论研究是强夯法研究的前提,意在分析强夯法
的作用机理和影响因素,从而合理的评价强夯法处理阜朝高速公路路基的加固深度;试
验研究主要通过大量的室内外试验,确定路基土的物理力学特性、黄土路基的湿陷性和
强夯法加固湿陷性黄土路基的效果。
在辽宁西部湿陷性黄土路段修筑高等级公路还是首次,本文所采用的试验研究在为
强夯法的研究提供了一条新的途径,研究结果对在其它湿陷性黄土地区修筑工程具有重
要的参考价值。

Applied Practice and Study of Dynamic Consolidation to the
Western Liaoning Province Collapsible Loess Ground
Abstract
Due to plex of dynamic consolidation and many uncertain factors existed in
ground the study and design of dynamic consolidation method mainly depended on analogy
and experience in past. Consequently, it is important to find a rational way to study dynamic
consolidation method. Based on the condition of the ground improving in freeway Fuchao,
the thesis analyzes the mechanism and factors of dynamic consolidation, and conducts the
systematic study of collapse loss ground improved with dynamic consolidation method by
experimental study and numerical simulation.
This thesis includes the theoretical study, experimental study and numerical simulation
of the ground improved with dynamic consolidation method. Theoretical study is the premise
in study of dynamic consolidation method, and the study is to analyzes the mechanism and
factors of dynamic consolidation, thus rationally assess the depth of improvement in freeway
Fuchao. Experimental study defines the indexes of physics mechanics and the properties of
collapse loss ground, and the effect of improvement in freeway Fuchao, in the same time,
experimental study offers rationally mechanistic parameters for numerical simulation.
Numerical simulation obtains the condition of displacement, stress and str
