Introduction

Prof Sheng is now acknowledged as an international leader in unsaturated soils research and has been invited to deliver plenary keynote lectures at major international conferences. For example, he was invited to deliver a state-of-the-art General Report at the 5th International Conference on Unsaturated Soils. He was awarded the prestigious John Booker Medal for his outstanding contribution in understanding the mechanics of unsaturated soils and frozen soils, at the 14th International Conference of IACMAG (Kyoto, 2014). He co-edited a Special Issue on unsaturated soils in the journal Computers & Geotechnics, and co-chaired the 5th Asian Pacific Conference on Unsaturated Soils. He serves in the Technical Committee of Unsaturated Soils in the International Society of Soil Mechanics and Geotechnical Engineering, and in international scientific committees of almost all international and regional conferences related to unsaturated soils. 

Prof Sheng has made significant contributions in this broad field, particularly in developing accurate, robust and fast numerical algorithms.

Prof Sheng’s PhD research was on developing theoretical models and computer software for predicting frost heave and thaw weakening in freezing soils. The computer software PCHeave developed by Prof Sheng was considered as the only one working properly for simulating frost heave in field conditions. His PhD research was awarded the ‘Stora Pris’ (the First Prize) by the Nordic Hydrological Society (NHF). He has recently been involved in studying the frost heave problems in high-speed railway embankments on seasonally frozen grounds in China and made important contributions towards understanding these problems. In 2014, Prof Sheng was awarded the John Booker Medal for his outstanding contributions in understanding the mechanics of unsaturated soils and frozen soils.
