摘要：
LTD-2100 type ground penetrating radar has its own unique data storage format, and the acquisition data is stored in lte format. This article explained in detail the data of lte format, especially illustrated and analyzed the header file parts of the radar data in tabular form. With a practical engineering as an example, the application of Matlab achieved a goal to read the ground penetrating radar, create a graphical user interface (GUI) and display the GPR data on graphical user interface. The actual data processing shows the effectiveness and practicality of the processing technologies.
摘要：
Energy transfer of pile body in foundation is considered by the energy balance equation of pile unit. Bilinear model is used to calculate the pile side load transfer, and trilinear model to calculate the toe resistance load transfer. According to the deformation coordinating relations, pile load-settlement curve analysis method is obtained. Comparing the in-situ and calculation data, the results show that they are basically consistent. The conclusions are pile bearing properties can be analyzed reasonably by this method, and the calculation results can provide a reference to engineering practice.

摘要：
Rock deformation and unstable failure of slope is controlled by weak structural plane whose identification and evaluation is greatly influenced by deformation failure prediction of slope and design treatment. Based on the propagation characteristics of acoustic wave in shaft lining strata, attenuation of stoneley wave and inherent attenuation of strata are analyzed and permeability relationship among shaft lining strata is researched. The relationship between reflected stoneley-wave intensity and the width and filling ability of strata crack is studied. By application example of landslide investigation, attribute parameters and characteristics of acoustic wave are discussed. Strata division, the practicability and accuracy of recognition for fracture and holes evaluation and mechanic characteristics of rock mass also are studied.
摘要：
The original plan is to use vibro-stone column composite foundation to treat a large oil tank foundation. The result of strengthening is not satisfactory because of some factors, such as difficulty to control quality and long construction period etc. Treated ground can not meet the design requirements. The key in treatment design of tank foundation lies in bearing capacity and deformation of foundation, especially in non-uniform deformation. Through the analysis of site conditions, composite foundation of CFG piles is adopted. It is designed according to strength and deformation of dual control theory. Experimental results show that the compound used in foundation design is appropriate.
摘要：
Lateral variations of the karst of deep buried tunnel engineering is big. The heterogeneity of it is strong. The tunnel is combined with Changsha Rail Transit Line 2 at one section of the first phase construction. Under the urban environmental conditions, it is considered to use auxiliary seismic wave imaging method assistanting with Rayleigh surface wave method. It is the detection and prediction method of comprehensive geological analysis of karst hazard, which identified the underground targets of deep buried tunnel effectively. To avoid a single technique multiple solutions, it can reflect the complexity of karst formations geological features objectively. Therefore, it can reduce the risk of drilling and take appropriate treatment measures to provide adequate and reliable basis.
