| dc.description | Preface: This report is one of a number of similar reports on studies of the construction and behavior, from a foundation and soil mechanics stand-point, of recently completed structures in the Lower Mississippi Valley Division. The purpose of the studies is to compare field experience and performance with design predictions, and from such comparisons and observations gain information and experience that will be valuable in the design and construction of future projects in the Lower Mississippi Valley. These studies are being made for the President, Mississippi River Commission, by the Waterways Experiment Station. Structures being studied are those for which foundation and soil mechanics investigations were made and design was prepared by the Waterways Experiment Station. The studies discussed in this report concern the construction and behavior of the Morganza Floodway Control Structure, and its adjoining embankments which serve as a main-line levee along the west side of the Mississippi River and also carry the Port Allen Branch Line of the Texas and Pacific Railroad, and Louisiana State Highway No. 30. The structure is located adjacent to the Mississippi River approximately 35 miles northwest of Baton Rouge, Louisiana, and 3 miles northwest of Morganza, Louisiana. The Morganza Floodway Control Structure was designed by the Mississippi River Commission and was built under the supervision of the New Orleans District, CE. Initial construction of the combined embankment was started in 1941 but was stopped in 1943 because of cessation of civil works during World War II. Work on construction of the adjoining embankments was resumed in December 1949; these embankments were essentially completed in January 1954. Pile tests to determine the size and allowable loading for the pile foundation beneath the structure were performed during the summer of 1949. Preload fills to reduce differential settlements at the abutments for the structure were placed at the south abutment in November 1949 and at the north abutment in July 1950. Driving of the pile foundation for the control structure proper was started in October 1950 and completed in August 1951. Work on the superstructure was also begun in October 1950 and was completed in February 1953. The first train crossed the structure on 18 November 1952 and highway traffic will probably begin in the latter part of 1954. Observations of settlement plates and hubs, piezometers, and movement markers placed in and beneath both the embankment and control structure were made during construction and have been continued up to the present time. It is planned to continue these observations and to analyze and report any future pertinent data in the form of appendices to this report. The studies and analyses of data presented in this report were made by Mr. C. I. Mansur, and Messrs. John A. Focht, Jr. and William Emrich (formerly of the Waterways Experiment Station). The field explorations were under the supervision of Mr. T. B. Goode. The studies were performed under the general direction of Messrs. w. J. Turnbull, w. G. Shockley, and$. J. Johnson (formerly of the Experiment Station), Soils Division, Waterways Experiment Station. This report was prepared by Mr. Mansur. Data on construction procedures and engineering measurement devices were furnished by Messrs. M. G. Chitty, H. A. Huesmann, and John w. Harris of the New Orleans District, CE. This report was reviewed prior to publication by Messrs. Huesmann and Harris of the New Orleans District, and Messrs. Howard B. Gray and E. H. Eckler, Jr., of the Mississippi River Commission. | - |
