Abstract

As a crucial component of urban transportation systems, municipal roads have their foundation treatment quality directly related to road service life and operational safety. Taking a municipal road project as an example, this paper details the application of cement-soil mixed piles in soft soil foundation reinforcement under complex geological conditions such as loose strata, high water content, and insufficient strength. Firstly, the basic principle of cement-soil mixed piles is expounded, emphasizing that they improve foundation bearing capacity and stability by forming a well-integrated and appropriately strong consolidated soil layer through physicochemical reactions between cement and soft soil. The latter then analyzes these core technical points from four dimensions of construction preparation, process flow, quality inspection and construction precautions respectively to provide a technical basis for high-quality construction in municipal road projects.
