Foam lightweight soil is a new type of material appearing in recent years, whose advantages are paid more and more attention to by engineers and it will have broad application prospect in the engineering. An in-depth study application of foam lightweight soil in the complex of railway soft soil foundation treatment what based on a railway foundation project in Tianjin, this paper discusses the actual application state of foam lightweight soil in handling of special railway soft soil foundation. Through in-depth analysis of the advantages of a foam lightweight soil, optimization of construction replacement thickness and moisture density, discussion on construction of it, we can find large advantages of foam lightweight soil as replacement material in the complex railway soft soil foundation treatment, and provide new ideas about processing complex soft foundation.

Municipal road and bridge engineering is an important part of the transportation road construction in the city. Its construction quality directly affects the transportation quality and driving safety of the whole municipal road traffic. Among them, the foundation engineering of municipal road and bridge engineering is the main construction link. In the current municipal road and bridge construction process, it is often affected by many factors, leading to the reduction of the construction quality of municipal road and bridge engineering, especially the construction treatment of soft soil foundation in the foundation engineering, which is the main factor directly affecting the construction quality of municipal road and bridge. This paper first introduces the definition and relevant characteristics of soft soil foundation in the construction of municipal road and bridge engineering, and expounds the influence of soft soil foundation on municipal road and bridge engineering, and then analyzes the application of soft soil foundation treatment technology combined with the basic treatment ideas of soft soil foundation in the construction of municipal road and bridge.

Powder Spraying

The foundation settlement of soft soil highway engineering is too large, resulting in pavement wave-like because of differential settlement between the structure and adjacent soft soil foundation, which seriously impacts on traffic safety. Considering the soft soil foundation in the foundation treatment methods of CFG pile, sand bag well, powder spraying pile, we analyze differential settlement on the degree of influence structure internal force distribution, then provide the reference for the design and calculation.

On the background of one railway freight yard in Xiao Yong railway , and firstly the use of thin-walled tubular pile is determined in railroad yard through the comparison with other methods in the soft foundation reinforcement. Secondly, the effect of the soft-soil foundation reinforcement combined with the numerical simulation and the measured data is analyzed. Finally, it is defined that the thin-walled tubular piles has good value in the treatment of the high-filling railway yard, and it also can provide a new method for the improvement of the soft subgrade in railway freight yard.

The application of vacuum preloading for soft foundation treatment in grain storage is introduced from its principle，design，construction and the inspections. Its obvious effect is proved by example. The east coast of China is the most developed economical area and major grain and oil manufacturers. Many grain and oil depots have been established. However, in the places where the depots located, soil is soft dirt with low strength grade, high compressibility, small permeability and high possibility of plastic flow, has increased difficulties of grain and oil depots foundation construction. Without enough knowledge of soft soil and lacking of proper foundation construction method and good technology, depots may slip due to foundation’s erosion, and big settlement. If the structure slips, equipments for aeration, dehumidifier, antivirus equipment cannot work well. Based on the statement above, reasonable and effective methods for soft soil foundation work is the key point for construction of high quality and high standard grain and oil depots. This paper mainly discussed when we do depots construction work on the soft soil foundation, exact calculation, construction method and result test of fasten method for the soft foundation under the vacuum circumstance of preloading.
