On the characteristics of fires in the underground buildings and the measures against them;

The radon concentrations in underground buildings in some coastal cities were surveyed by using solid state nuclear track detector(SSNTD's) CR-39.

This paper proposes a new approach to determine dynamic thermal load of exterior envelope of underground buildings by means of a heating box and points out that this method is a better way than others by analyzing its principle and technological feature etc.

On the damage caused by smoke of underground building and measures;

Computer simulation and optimal control of underground building;

Predicting the volume of natural air change in underground buildings by the Monte Carlo technique;

Research on simulation software for heating and air conditioning load of underground spaces;

Research on application of the WSHP air conditioning system to underground space;

Numerical analysis of dynamic heat transfer through walls of underground structure;

Dynamic simulation of heat transfer through envelope of shallow underground structures;

Numerical simulation of an underground structure under a hypothetic terrorist bombing;

Probing at urban underground construction space shape design;

The trends of underground constructions can be expected as the development of housing and public constructions suitable for peacetime or wartime, the development of multifunctional highway network, the development of medium-sized or small-sized energy-saving constructions and the development of underground constructions for public services.

Based on investigation and estimation of acoustic environment for more than 100 underground constructions in 21 cities( including underground markets , hotels , guest houses , multifuctional halls , cinemas , conference halls , headquarters of civil air defence , dining halls , dancing halls, urban underground traffic tunnels etc.
