“…In overpass sections, retaining walls are often installed, and subway construction will not only affect road safety [1][2][3], but also threaten the stability and safety of the retaining walls. At present, there have been many studies on the stability of retaining walls, including the stability of retaining walls under static loads [4][5][6], the dynamic response of retaining walls [7][8][9][10][11], the behavior of retaining walls affected by deep excavation [12,13], and the time-dependent behavior of piles and retaining walls as a result of excavationinduced soil movement [14]. ese studies have made many achievements in terms of the stability of retaining walls.…”

Anzhen Bridge Station of Beijing metro line 12, which adopts a separated-island platform constructed by the undermining method, passes along the retaining wall of the North Third Ring Road. A numerical simulation method is adopted to study the deformation laws of the retaining wall under the influence of station construction. The simulation data show that the affected retaining wall will have large settlement and tilt, and countermeasures must be taken. Four countermeasures are formulated, and their control effects are analyzed. The calculation results show that the combination of anchor cables and waist beams can effectively control the tilt of the retaining wall, but the control effect on the absolute settlement is not obvious. The control effect of isolation piles is better than that of foundation grouting. The joint control method of anchor cables combined with waist beams, isolation piles, and deep hole grouting makes the deformation meet the target, and according to this measure, a concept of joint control aiming at the influence of the “source,” “propagation,” and “object” is proposed, which can provide a reference for similar projects with a great difficulty in deformation control.

Clay soils provide several challenges for geotechnical and civil engineers. This type of soils has a low strength, high plasticity and can cause damage to the road pavement such as crack and soil strength reduction. Thus, require stabilization method. Continue of research and investigations have been done to find other alternative in soil stabilization that eco-friendly. Geopolymer, one of the alterative eco-friendly soil stabilization method offering small swelling potential and outstanding adhesion to soil properties, which could be an effective soil stabilizer. Geopolymer is a reaction that chemically integrates minerals that involves naturally occurring silicoaluminates sources. The geopolymer synthetized from soil, fly ash, ground granulated blast slag and an alkaline solution made from sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). The characterization testing includes physical properties, X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) to examine the physical properties, elemental chemical composition, mineralogical properties, microstructure, and bonding chemical of the raw material, respectively. Based on the characterization result, the soil, fly ash and ground granulated blast slag consists mainly of silica (SiO2) and alumina (Al2O3) which make it suitable to be used as raw materials for geopolymer formation. This paper presents a characterization analysis of soil, fly ash and ground granulated blast slag as raw materials for soil stabilization application using geopolymerization method.
