Negative skin friction (NSF) of piles in recent filling or soft area is an important effect factor pile bearing capacity. Since field experiments on NSF are time consuming and it difficult to large surcharge loads experimental research, a unified calculation method positive/negative was established based the effective stress for investigation. The closed-form analytical solutions calculating corresponding plastic elastic state were derived respectively. Meanwhile, axial load single under...
The authors investigated the performance of an inclined threelayer cover with capillary barrier effect (CCBE) system comprising silt, sand, and gravel, subjected to a continuous heavy rainfall (Zhan et al. 2014). They compared numerical results analytical solutions respect effective length lateral diversion three-layer CCBE system. comparison indicated that solution proposed by Stormont (1996) is relatively conservative. It should be noted Stormont’s only applicable two-layer In discussers’...
Secant pile walls reinforced with steel I-beams are widely used worldwide. Although ground surface settlement caused by the installation of secant has been investigated, there is minimal data available on due to extraction from walls. This note aims investigate effectiveness cement slurry refilling reducing settlements during I-beams. Measured and without reported, discussed, explained. Two different influence zones I-beam can be identified. Ground minimized slurry. By using such a...
Phase I project of the Beijing CITIC Complex was completed in 2010. Its pipeline drainage system built to convey a 1-year storm event. But new regulation heightened design standard three years for any development. Phases II and III projects upstream site are under planning, their conveyance systems connect project. Therefore bottleneck is how runoff 3-year event without causing downstream flooding. This paper discusses various solutions including construction underground detention tanks...
The goal of this work is to propose a hardware-in-the-loop, human-in-the-loop agent-based simulation which incorporates the human crowd characteristics and behaviors captured by computer vision techniques, for an effective control using unmanned vehicles (UVs). Three major functions needed in our autonomous surveillance system include: 1) detection, 2) modeling, 3) tracking. proposed communicates with detection module UVs' onboard real-time, developing plans number simulated...
Vehicle jolting at bridgehead on soft ground has seriously affected the normal usage of highway. At present, Asphalt Overlay is adopted to eliminate non-uniform differential settlement in used super highway China. Therefore, it's very important analyze causes vehicle and specify its prevention measure. Proceeding from analysis mechanism reinforcement FCB, this paper specified physical mechanical properties, analyzed summarized effects reinforcement. Through engineering example ShenJiaHu...
Pore gas pressure in soil is an important parameter many geoscience applications such as evaluating the effects of trapped pore on water infiltration through mass, optimizing design extraction wells landfills and assessing performance landfill covers reducing emission. In addition, it has been observed that affects slope stability unsaturated soils. However, build-up induced by generally ignored most analysis assuming to be zero. Therefore, measurement soils crucial better understand...
This paper reviews recent advances in 3D on-chip electrostatic discharge (ESD) protection design for integrated circuits (IC). Traditional ESD relies on PN-junction-based structures, which have inherent disadvantages including fixed triggering and parasitic effects. New mechanisms nano crystal dots crossbar concepts, provide alternative non-traditional solutions enabling post-Si field programmable above-IC circuit designs. The new concepts represent a paradigm change designs are potential to...
Abstract The difference in the shear strength and other characteristics of cohesive soil containing calcareous nodules (CSCN) between samples with large size corresponding scaling size, which is called effect, significantly affected by its nodule content (CNC) gradation composition. However, current researches rarely reveal influence CNC on effect samples. In this study, how why affects were explored. Then a method to reduce based reason for was proposed. Results show that correlation...
It is well known that the quality of sample significantly determines accuracy soil parameters for laboratory testing. Although sampling disturbance has been studied over last few decades, theoretical investigation due to penetration rarely reported. In this paper, an analytical solution estimating was presented using cavity expansion method. Analytical results in several cases reveal at different location along centerline experiences distinct phases strain during process penetration. The...
Due to the settlement hazards induced by soft clayey soils, vacuum preloading has been widely used all over world. Many studies focus on process of application but removal is generally ignored. Different from observations surcharge preloading, ground rather than heave occurred during removal. In this study, a stress-controlled triaxial test was carried out simulate both processes and applied soil hence mechanism discussed. Compressive axial strain observed decrease isotropic stress that...
