TL;DR: In this paper, the chlorite schist sample from the Jingping Ⅱ Hhydropower Prjoect on Yalong River was saturated by the saturated NaCl solution and the distilled water, its uniaxial and conventional triaxial test was done in the RMT and MTS test machine, in which the strength index of saturated and dry state in different solutions was obtained.
Abstract: The chlorite schist sample from the Jingping Ⅱ Hhydropower Prjoect on Yalong River was saturated by the saturated NaCl solution and the distilled water,its uniaxial and conventional triaxial test was done in the RMT and MTS test machine,in which the strength index of saturated and dry state in different solutions was obtained.Compared with its mechanical parameters' change and analyzed its micro-mechanism of electric double layer,results showed that the strength of chlorite schist under water was decreased obviously,which showed its softening under water because of the influence of its electric double layer,the more the thickness of electric double layer was,the more the decrease of the chlorite schist's strength was,vice versa.
TL;DR: In this article, the authors summarized the history of bolt's testing technique, two tilpes of testing method are describled in detail: i.e. drawing test and stress wave reflection method.
Abstract: Bolt has been used widely in geo-engineering all over the world in recent years, the testing technique of bolt develops quickly too. This paper summarizes the history of bolt’s testing technique, two tilpes of testing method are describled in detail:i.e.drawing test and stress wave reflection method. The prospect of bolt’s testing technique is mentioned through combining the test technique with wavelet analysis and artificial neural network.
TL;DR: Based on the changing of laterally frictional resistance and the difference of relative motion along soil of adjacent piles, the authors offers the opinion that real anti-sliding pile is replaced by the model of equivalent anti-siding pile, and analyses the forming process of soil arching between adjacent piles.
Abstract: First, based on the changing of laterally frictional resistance and the difference of relative motion along soil of adjacent piles, this paper offers the opinion that real anti-sliding pile is replaced by the model of equivalent anti-sliding pile, and analyses the forming process of soil arching between adjacent piles. Then based on the loading features of soil arching, it is the most remarkable soil arching unit of tight function of the wedge that is arching bottom-the effective soil arching, and it is not the foremost that soil arching extends naturally. Finally, on the premise of this analysis and assumption, the mechanics model of parabola type soil arching have set up, get the balance condition and strength condition that the biggest spacing between adjacent piles must be met.
TL;DR: The predicting result indicates that the model proposed here has fast approximation performance and high precision, which provide a valuable means for ground settlement prediction around deep foundation pit.
Abstract: In this paper,wavelet neural networks are used for predicting the ground settlement around deep foundation pit. An effective predicting method is put forward,and set up the wavelet neural networks model for ground settlement prediction. The predicting result indicates that the model proposed here has fast approximation performance and high precision,which provide a valuable means for ground settlement prediction around deep foundation pit.
TL;DR: In this article, the root-soil complex with herbs bermudagrass root was tested by using the direct shear test, and the results showed that the shearing strength of soil was improved due to the herb bermuda root system and increased with the increasing of its root weight.
Abstract: Aimed to study the shearing strength regularity of it on the condition of different root weight and vertical pressure,the root-soil complex with herbs bermudagrass root was tested by using the direct shear testThe results showed that the shearing strength of soil was improved due to the herbs bermudagrass root system and increased with the increasing of its root weight,but there was the optimal root weight range,when it was further increased the shearing strength of root-soil complex wasn't increased obviously
