Soil samples from natural forests and adjacent farmland were analyzed to investigate the dynamics of soil organic matter of red soil in Southern, China. Based on the δ13C values and the content of soil organic matter, the data indicated that the turnover of soil organic matter under the virgin forest was slower than that under cultivation. Soil organic(More)
Safety construction of deep foundation pit in narrow space is one technology difficulty. Analysis on the deformation of adjacent building during excavation and supporting is the key factor. Taking the deep foundation pit, supporting structure and surrounding buildings as one system, this paper applies the numerical simulation analysis method to carry out(More)
The dynamic stability of structure is attracting more and more attention. How to control the dynamic instability effectively is a new subject; piezoelectric smart structure makes itpsilas possible. The research of dynamic stability involves some subjects, and was developed recent decades. The birth of intelligent structure gives a new way of the active(More)
