Construction Method and Numerical analysis on the bearing capacity of the large diameter and abyssal pile located in complex karst area Jin Yi1,a, Guojing He1,b, Sisi Liu 1, Zhiyong Li2 and Zuen Zheng2 1 Central South University of Forestry and Technology, Changsha 410007, Hunan , China 2Traffic Science Research Institute of Hunan Province, Changsha 410001, Hunan , China ayjcc1978@163.com; bcegjhe@hotmail.com(Corresponding author) Keywords:karst region;large diameter and abyssal pile;finite element model; construction method; Abstract.
The contact of stratigraphic unit and pile shaft unit is calculated by nonlinear three line load transfer function, take zero as the contact parameter of the karst cave, consider the compression of pile shaft only, and tip resistance is calculated by nonlinear material hardening model.

Production planning department, through the production planning (including Master Production Schedule (MPS) and Material Requirement Planning (MRP))module, starts on the production task for first time distribution, and does production workshop’s redistribution of production task by real-time capacity balance module.
This paper proposes, in the process of microscopic distribution, enterprises can combine with multi-process scheme base and real-time resource information, and use the PSO algorithm to solve the multi-process and multi-objective scheduling problem; it will assign the production task after MPS/MRP processing to specific material distributions, equipment selections and personnel arrangements.
The integration interface of the job shop scheduling module in the production management with other modules of ERP module is as follows: (a) the interface with wage management module, wage management module can take the wage amount in wage summary table by time or by the piece as the basis of wage settlement; (b) the interface with cost management module, cost calculation needs to collect the specific data of the working procedure report to calculate the true cost of work in process(WIP), the procedure’s scrap number is also a part of cost calculation; (c) the interface with inventory management module, it can make the procedure’s material requisition through the working procedure plan or working procedure flow card, or can also generate completion warehousing entry according to the transferring list of the ended procedure, procedure flow card report and outsourcing Fig.3 Gives an integration chart of workshop scheduling system and ERP system.

Introduction Laser induced plasma spectroscopy(LIBS) is gradually on the rise in recent years, a broad-spectrum detection technology, it is one of the atomic emission spectrometry using a focused laser pulse in the material surface,To form a local high temperature, leading to partial sample vaporized, resulting in the sample atoms or molecules in an excited state or ionized thereby plasma plume is formed on the sample surface.
Excited state atoms and ions in the plasma portion of the energy in the form of light in the relaxation processradiation, this radiation with a significant element feature information. however this characteristic lines tend to have a very narrow linewidth, and therefore need to be collected by high-resolution spectrometer, recording and analysis of radiation spectrum, in order to achievepurpose of the qualitative and quantitative analysis of the chemical elements in the solid, liquid and gas samples., the LIBS technology applications areas in addition to the traditional chemical analysis,There also includes environmental monitoring, industrial line measurement, biotechnology, heritage conservation, nuclearindustrial, deep space exploration, marine science, surface analysis, and many other areas.In this paper, a self-made high-resolution miniature fiber optical spectrometer.
Taking into account the liquid and solid materials LIBS signal is weak, it ultimately has a high sensitivity ILX554B changed detector has the following characteristics: effective pixels number 2048; pixel size of 14 um * 56 um; single 5 V power supply; ultra-high sensitivity; built-in timing generator and clock drive; built-in sample-and-hold circuit; maximum clock frequency of 2 MHz.

Preload relaxation is a complex phenomenon and the amount of preload relaxation is quite difficult to characterize since it must consider the materials, loading, and physical environment, etc.
On relaxing the tension, the rod stretch drops to around the nominal value, resulting in utilization of only the half yield strength of the rod material.
