Abstract:
The classified method and the classified standard about the site classification in the exist national standard are discussed in this paper, and some views and suggestions are proposed based on the discussions.

Abstract:
The unscience and the properties of multisolution of the value of c and φ by graphic solution, and the advances (unique) and lacks (mechanism) of the value of c and φ by standard(GBJ7-89) are analysed in this paper. A new method to determine the value of c and φ by using the absolute value of the least relative error is proposed,The reliability of the value of c and φ are improved by this method.

Abstract:
The requirements for the bearing stratum at the pile tip in the standard of pile foundation arc brokenthrough and ths applying region is expended by the successful practice# The aim of this paper is to emphasize the important of the selection of the bearing stratum at the pile tip and the pile type during the processing of the soft foundation and to provide inference for the revision of the standard of the structure pile foundation.

Abstract:
An approximate calculation method of the superimposed stress of the foundation under the irregular loading area is introduced in this paper. This method is convenient to use and the accuracy required can be obtained

Abstract:
According to the ways and characteristics of fissure groundwater acting on the slope, the effects of the movement of fissure groundwater in the evaluation to the rocky slope stability are discussed, and the quantitative method of evaluation about the effects are also given in this paper.

Abstract:
Through the practical example of the ground lofting of the axes of the river crossing tunnel in one seaside city, the selection of the control scheme, the lofting method and the accuracy, as well as the problems in operation and its solution are all discussed in this paper.
