Introduction As we all know, the underground space development has been a highlight of the civil engineering in the new century.
Because of this reason, the author create three-dimensional model of the subway with different horizontal distance to the frame structure, working out forces' variation of the frame structure caused by subway excavation, so as to provide a channel for engineering and technical staff to understand function mechanism, then contribute to solving similar problems with certain value of enlightenment.
This text has a more comprehensive coverage of the influence between the subway and the frame structure in different situations, will enable engineering and technical staff a more comprehensive understanding on this issue, and provide guiding significance for solving the engineering problems to some extent.

Engineering Economic Benefits of Geosynthetics Geosynthetics are widely used in geotechnical engineering and have a great impact on the development of geotechnical engineering.
A large number of engineering practices show that geosynthetics can effectively save engineering materials, reduce engineering costs, protect the environment, and achieve better economic and environmental benefits.
Geocell is widely used in geotechnical engineering.

The different engineering involves in different range of loess mass and structure fissures with different sizes, types and ranks have different effects on engineering loess mass.
So in engineering practice, we need prioritize structure fissures and pick the most important one or ones to analyze their effects on the properties of engineering loess mass.
So it is necessary to take special surveying and hazards assessment to the fissures before engineering construction and set required secure distance away from these structures for engineering site.
These structure fissures usually breakthrough engineering loess mass whose characteristic controlled by the fissures and their activities mainly affected by engineering load, gravity and environment(like groundwater).

Thermal fatigue occurred in many engineering constructions made of polymeric composites subjected to the intensive loading and vibrations.
These materials used lately only for electromagnetic isolation and for the elements, which are not subjected to intensive loading and high stresses found now very responsible applications in civil engineering, military industry, aircraft and spacecraft industries, shipbuilding and machine building industries, etc.
The self-heating effect is often omitted during designing of composite elements, which may cause catastrophic consequences in engineering practice.
Basing on literature survey it could be concluded, that the effect occurs in many engineering solutions and constitutes real danger during operation of composite elements.
Besides presented engineering problems, where the self-heating effect occurs there are many other constructions subjected to the occurrence of the effect.

This implies that the construction of the proposed Qinghai-Tibet Express Highway will have to use new techniques of cooling the embankment and underlying foundation soils instead of ordinary engineering measures by increasing simply thermal resistances of embankment [2-7].
In practical engineering, the influence of many parameters, such as grain size of crushed rock matrix, porosity and air-permeability of crushed rock layer, thickness of crushed rock layer, asphalt surface layer, environmental condition, engineering and geological conditions, etc., on the cooling capability of winter-time natural convection in the highway embankment is of prime importance [8-14].
