Application of Geodetic Measuring Methods for Reliable Evaluation of Static Load Test Results of Foundation Piles
remote sensing Article Application of Geodetic Measuring Methods for Reliable Evaluation of Static Load Test Results of Foundation Piles Zbigniew Muszy ´nski 1,* and Jarosław Rybak 2 1 Faculty of Geoengineering, Mining and Geology, Wrocław University of Science and Technology, 50-370 Wrocław, Poland 2 Faculty of Civil Engineering, Wrocław University of Science and Technology, 50-370 Wrocław, Poland; [email protected] * Correspondence: [email protected] Abstract: Geodetic measuring methods are widely used in the course of various geotechnical works. The main purpose is usually related to the location in space, geometrical dimensions, settlements, deflections, and other forms of displacements and their consequences. This study focuses on the application of selected surveying methods in static load tests (SLTs) of foundation piles. Basic aspects of the SLT are presented in the introductory section, together with the explanation of the authors’ motivation behind the novel (but already sufficiently tested) application of remote methods introduced to confirm, through inverse analysis, the load applied to the pile head under testing at every stage of its loading. Materials and methods are described in the second section in order to provide basic information on the test site and principles of the SLT method applied. The case study shows the methodology of displacement control in the particular test, which is described in light of a Citation: Muszy´nski,Z.; Rybak, J. presented review of geodetic techniques for displacement control, especially terrestrial laser scanning Application of Geodetic Measuring and robotic tacheometry. The geotechnical testing procedure, which is of secondary importance for Methods for Reliable Evaluation of the current study, is also introduced in order to emphasize the versatility of the proposed method. -

Bidirectional-cell tests were performed in Singapore on four bored piles in a residual soil and underlying weathered, highly fractured bedrock called the Bukit Timah Granite formation. Two of the piles were 1.2 m diameter, uninstrumented, and 28 m and 38 m long. The other two were strain-gage instrumented, 1.0 m diameter piles, both 37 m long. The latter tests combined the cell test with conventional head-down testing. Analysis of the test results indicated that the pile toe stiffness was low. The evaluation of the strain-gage data showed that the pile material modulus was a function of the induced strain. The desired axial working load was 10 MN, and the combined cell and head-down tests correlated to a head-down test with a maximum applied load of 38 MN, which, although smaller than the ultimate resistance of the piles, was taken as the capacity of piles constructed similar to the second set of test piles at the site. -

Borrow Pit Volumes**
EARTHWORK CONSTRUCTION AND LAYOUT **BORROW PIT VOLUMES** When trying to figure out Borrow Pit Problems you need to understand a few things. 1. Water can be added or removed from soil 2. The MASS of the SOLIDS CAN NOT be changed 3. Need to know phase relationships in soil….which I will show you next Phase relationship in Soil This represents the soil that you take from a borrow pit. It is made up of AIR, WATER, and SOLIDS. AIR WATER So if you separated the soil into its components it would look like this. It is referred to as a Soil Phase Diagram. SOIL When looking at a Soil Phase Diagram you think of it two ways, 1. Volume, 2. Mass.

Soil Plugging of Open-Ended Piles During Impact Driving in Cohesion-Less Soil
Soil Plugging of Open-Ended Piles During Impact Driving in Cohesion-less Soil VICTOR KARLOWSKIS Master of Science Thesis Stockholm, Sweden 2014 © Victor Karlowskis 2014 Master of Science thesis 14/13 Royal Institute of Technology (KTH) Department of Civil and Architectural Engineering Division of Soil and Rock Mechanics ABSTRACT Abstract During impact driving of open-ended piles through cohesion-less soil the internal soil column may mobilize enough internal shaft resistance to prevent new soil from entering the pile. This phenomena, referred to as soil plugging, changes the driving characteristics of the open-ended pile to that of a closed-ended, full displacement pile. If the plugging behavior is not correctly understood, the result is often that unnecessarily powerful and costly hammers are used because of high predicted driving resistance or that the pile plugs unexpectedly such that the hammer cannot achieve further penetration. Today the user is generally required to model the pile response on the basis of a plugged or unplugged pile, indicating a need to be able to evaluate soil plugging prior to performing the drivability analysis and before using the results as basis for decision. This MSc. thesis focuses on soil plugging during impact driving of open-ended piles in cohesion-less soil and aims to contribute to the understanding of this area by evaluating models for predicting soil plugging and driving resistance of open-ended piles. Evaluation was done on the basis of known soil plugging mechanisms and practical aspects of pile driving. Two recently published models, one for predicting the likelihood of plugging and the other for predicting the driving resistance of open-ended piles, were compared to existing models. -
